Biomes and Organisms that Live Within Them Essay Example

Biomes and Organisms that Live Within Them Essay Example Biomes and Organisms that Live Within Them Paper Biomes and Organisms that Live Within Them Paper Biomes are large part of the earth that supports its existence. It refers to terrestrial habitats that are best differentiated according to their type of weather, fauna and flora (WorldBiomes, 2003). It was also defined by Campbell as the world’s major communities grouped according to its major vegetation and acclimatization of organisms to that specific environment (UCMP, 1996). Biomes were altered due to human activities and conservation of biomes is a major concern nowadays. Â  In many parts of the world, different types of biomes are divided depending on the type of climate it contains. There are many ways of categorizing the types of biomes in our environment. According to WorldBiomes (2003), there are five major biomes that are classified into aquatic, desert, forest, grasslands, and tundra. Forest Biomes characterize the biggest and most ecologically complicated systems since it contains variety of species, trees, mammals, reptiles, amphibians, invertebrates, insects and micro-organisms which has different type of weather and environment. Forest biomes have been a major area of concern in conservation due to massive forest degradation in the past and at present. Specifically boreal and rainforest are being deforested at a distressing rate of disappearing species of plants and Giant horsetails, club mosses, and ferns which grew up to 40 feet tall were the original forest species in the world and ancient plants and arthropods also inhabited the land (UCMP). It continued to exist and changed through time, various types of species evolved in which gymnosperms dominated the forests in the early periods of Paleozoic and Triassic period. As time passed by, the first flowering plants in the Cretaceous period come into sight simultaneously other kind of species emerged like insects, birds, and mammals. Due to some changes in the environment, species and forests were also altered giving way to a new kind of forest to grow in the surrounding. One-third of earth’s land area is occupied by the vastness of forests. Today, it is divided into many kinds of forests but there are only three major types which are grouped according to latitude, it includes tropical forests which is characterized by the presence of evergreen angiosperm trees located in warm and damp conditions, temperate rain forests are typified by evergreen conifers or tree ferns located at mild and wet environment throughout the year, and boreal forests is the largest forest biomes and also called as the taiga biome which can be found in areas with cold climates and long winters. Most boreal forests are inhabited by different organisms, birds and mammals like deer, wolves, rodents, and a small number of reptiles. In the temperate forests, most of the organisms found are the smaller and cold blooded animas like snakes, turtles, amphibians and plant species includes maple, elm, oak, and cedar. While primate species, birds, insects, mammals, invertebrates, termites, vertebrates, orchids and moss are found in tropical rainforests. In the forest, the symbiotic relationship which refers to close ecological relationship between two or more different species or organisms that benefits from each other and may benefit at the expense of the other and in some cases neither organisms can gain an advantage, between birds and mammals and even fish for example likes to eat fruits from trees and when these fruits fell to the ground, the seeds that are taken by the animals are dispersed into different parts of the forest land and eventually the seeds will grow and produce more and more trees. Another example is the relationship between the bee and the flower which also inhabit the forest, bees soar from flower to flower to collect nectar which are the source of food of bees and in turn bees with pollen from their hairy bodies will drop it to the flower making it pollination complete. In this situation, both bees and flowers benefit from the said process. This type of relationship is an example of mutualism in which both species benefit from the activity. On the other hand, parasitic relationship involves only one species benefit from an activity and the other is harmed. Example of this is the relationship between the parasite (tapeworm) and animals like pigs and cows. Tapeworms are fragmented flatworms that live in the stomachs of animals and even humans, they dig up for food through the host’s digested food leaving the host with no nutrients. Parasitic relationship is also evident in plants where aphids usually attack and eat the sap from the plants. Commensalism is another relationship that exists in a forest biome where only one species can take an advantage and the other is unaffected. One of the best examples is the relationship between the grape vine and a tree, the grape vine is strongly attached to the tree and almost climbing to the canopy to support itself. It is true that the tree is not disturb from the vine not either the grape vine affects the trees.

Chapter question - Essay Example age, compatibility, complexibility, trialability, observability, impact on social relations, reversibility, communicability, time, risk and uncertainty, commitment and modifiability† (Edberg, p. 59). Relative advantage defines the measure of effectiveness and efficiency of a proposed innovation with respect to the old technology. A significant relative advantage will therefore motivate a faster adoption of the theory. Complexibility refers to the level of ease of applying a proposed technology. While a complex technology may delay implementation due to lack of implementation resources and determination of certainty over the technology, a less complex technology can be immediately implemented (Edberg, p. 59). Triability however defines the ability to test the technology, practically, before its adoption. Where such practical tests are possible, decision can be made on whether to adopt the technology or not. In cases where such tests are not possible, alternative approaches must be devised and this may delay adoption of the proposed technology. The impacts that the technology can have on the society are also important in determining how fast it can be implemented. This is because social responsibility measures must first be put in place before implementation of the technology. The other factors can also either speed up or delay implementation (Edberg, p.

Problems of global waste

Problems of global waste The caring for and management of global waste is a global concern for the Earth as the population of Earth grows, and places where waste is deposited becomes a problem. Waste of various kinds is a danger to human health, wildlife preservation, and the environment in a broad range of aspects including how waste affects water supplies, soil contamination, and hazardous environments that remain or become uninhabitable. As the human population grows, so does consumption, and with that consumption huge amounts of waste are formed. concerning the management and the future of how waste is handled locally and globally, as it is a global problem not just local. How people and wildlife can cope with or without a world filled with hazardous material left over from various human activities caused from their disposal of waste. municipal solid waste of most human households affect how we live and how we affect the environment. How medical waste that is thrown in places where it may come into conta ct with the human population and how it can spread disease. How hazardous waste that is perceived by the public as the most potentially dangerous waste, can prove to be fatal if left untreated in populated areas . Is the future of waste management that of recycling or turning waste into usable energy such as electricity and other powered devices. Waste problems do not only affect local environments but the global environments as a whole. Unfortunately when waste is put into landfills the waste does not disappear just because the human eye can no longer see it does not mean the earth and global habitats dont feel the consequences. There are many kinds of waste that effect the world. they are classified by their physical, chemical and biological characteristics of their compounds . Solid waste materials can contain less than 70% water. Solid waste can be materials as household garbage, industrial wastes, mining wastes, and oilfield wastes. Liquid wastes contain less than 1% solids. Liquid waste can contain high concentrations of salts and metals. Sludge is whats in between liquid and solid. Sludge is usually made up of 3% and 25% solids, everything else is water dissolved materials. Landfills affect pollution levels of the environment the contamination of groundwater and aquifers that are used for consumption by humans and anim als the leakage of waste and soil contamination methane gas caused by decaying organic wastes methane which is a greenhouse gas more potent and deadly than carbon dioxide it can cause severe problems for the local environment around the waste site they can also be disease zones can cause outbreaks of certain diseases to the surrounding area and problems of annoyance and health risks such as dust, pests, bad odor, and other problems. Alternative methods can help the environment such as waste reduction and recycling incineration of waste can also reduce waste problems but when waste is burned harmful substances affect our air quality and health. When Waste is burned in incinerators It is a more expensive alternative way of disposal than landfills. In the united states the EPA reported 118.5 million tons or 57 percent of the united states total waste were managed in landfills. Todays incinerators are capable of destroying around 99.9% of the organic waste material that are put into the furnaces. Also this can produce a form of usable energy for Numerous thermal processes that recover energy from the burnt solid waste. waste organizations burn wastes in incinerators to produce steam for energy and is cleaner. Garbage as plastic and other non organic substances burned in incinerators poisons water soil and the air. Areas of life that are near incinerators have objected to them because of fears of harmful pollution. There are drawbacks to the use of incinerators but it is one of the measures that can reduce organic waste problems. In the United states 33.5 million tons of waste or 16 percent total were combusted at high temperatures. Recycling methods are becoming more popular worldwide. Recycling can also be a way to gather energy through thermal treatment from using waste as a way to use for appliances, and too make boilers to produce steam and electricity in a turbine. When items that would be waste if not recycled can be reused and prevent waste of reusable mate rials, lowers the need to keep making more items that would be more waste, and keeps the environment safer than use of other waste management methods like incineration and to prevent water pollution from landfills. recycling has also lower greenhouse gas that is a major concern for our planet. Recyclable products are many items from glass, paper, metal, plastic, textiles, and electronics that are refurbished cleaned and gone through different checks to make sure they are safe for re-consumption. unfortunately recycling methods tend to be very expensive alternatives to traditional waste management and for this reason they are turned away for much more environmental damaging solutions. The Environmental Protection Agency reported that 56 million tons or 27 percent of Americas total waste were recovered by recycling. The EPA is encouraging recycling and that recycling in the united states has reduced the countrys total carbon emissions. Recycling has caused some controversy by critics as they often say that the practice is too expensive and not as effective as other methods as incineration which produces energy that is used more than the reused products that are saved from recycling and how landfills are becoming more organized and more environmentally friendly than in the past. To Methods to turn waste into energy as discussed with how incinerators create energy are called Waste-to-energy and is becoming increasingly popular as it turns harmful waste into energy in the form of heat of electricity from the incineration of the waste materials. This form of waste management produce electricity in the form of combustion or produce a combustible fuel in the form of ethane methanol methane and also synthetic fuels that can power various equipments. There are also some very new and developing technologies that produce energy from waste and other fuels without direct combustion like that of incinerators. These new forms of energy producing waste deduction have the poten tial to produce more electric power amount of fuel than would be by direct combustion. The converted fuel produce a higher combustion temperatures. A modern form of waste management is Plasma arc gasification it uses a very high electrical energy and the extreme temperatures created by an electrical arc gasifies. The arc converts waste into elemental gas and solid waste in a plasma converter. this method has been intended to be a generator of electricity, depending what the composition of input wastes are and to reduce the volumes of waste being sent to landfill mounds. Another method of making waste or other products into energy is gasification which converts carbon materials like coal and petroleum into carbon monoxide and hydrogen by placing the materials in a high temperature within a controlled setting of oxygen and steam. This forms synthesis gas and is a fuel. mechanical biological treatment system facilities is a sorting facility that takes care of biological treatment such as anaerobic digestion and composting . mechanical biological treatment facilities are designed to process household wastes along with commercial and industrial wastes.

Medication Errors Essay

When doing the job of nursing one of the most important aspects is patient safety. The biggest danger to patients is medication. A medication error is when the nurse gives a patient the wrong medication or the dose of medication could be wrong. The danger of the medication error is that it can lead to an over dose, a reaction, or even death to a patient. There are several things to know when dealing with medication errors like who should fill it out, who should receive a completed report, why would you fill one out, what is included, and what a near miss is. The first thing to know is that it is the responsibility of the nurse who made or discovers the medication error. Once the report is filled out then it is given to the unit nurse supervisor then forward to the QI department. There are several reasons why you would fill out a report such as: Omission error, Wrong dose, Wrong route, Wrong rate, Wrong drug, Wrong time, Wrong duration of treatment, Wrong patient, Wrong preparation of a dose, Incorrect administration technique. The most common things that cause medication errors are illegibly written orders, dispensing errors, calculation errors, monitoring errors, administration errors. When filling out a medication report you should describe the error or preventable adverse drug reaction and what went wrong? Was this an actual medication accident (reached the patient) or are you expressing concern about a potential error or writing about an error that was discovered before it reached the patient? Type of practice site (hospital, private office, retail pharmacy, drug company, long-term care facility, etc.). Generic name (INN or official name) of all products involved. Brand name of all products involved. Dosage form, concentration or strength, etc. Where error was based on communication problem, is a sample of the order available? Are samples or pictures available if requested? State your recommendations for error prevention. You also have to include your name, email, fax, address, title, phone, and location. A near miss is any Circumstance, process, or event that did not reach the patient, but has the potential to cause harm. It is considered a medication  error but one of the best turn outs of medication error is a near miss. There should never be any reason for medication errors but they do happen in real life.
