Extract of sample "Biogeochemical Cycles"

Download file to see previous pages The present research has identified that a nitrogen cycle consists of a gas phase and a mineral phase. Since plants require nitrogen as a mineral rather than a gas, they receive their requisite via biological nitrogen fixation, aided by bacteria. Legumes play an important role by giving them a home and transferring the fixed organic nitrogen, thus produced, in the ecosystem through food chains. Animals, for the purposes of energy, break down proteins and organic compounds and excretes the ammonium ion form of nitrogen. Either the plants reabsorb it or bacteria convert it into nitrate, hence creating an organic cycle. “The key processes in a carbon cycle are of respiration and photosynthesis. During the process of respiration, carbohydrates and oxygen in a combination, produces carbon dioxide, water, and energy”. Whereas, during the process of photosynthesis, carbon dioxide produces the carbohydrates and oxygen, back again. Besides being liberated by a plant, either the carbon remains in them when they die or animals eat plant and respire them back into the atmosphere through respiration. Moreover, either decomposer decompose actively cycled carbon in a dead organic matter to release it back into an atmosphere or the dead matter stays intact to form coal, oil or natural gas (fossil fuels). As per hydrogen cycle, since, the largest reservoir for hydrogen is water; electrons from H2O, H2S, and low-molecular-weight organic compounds reduce CO2 whereas the electrons from reduced organic compounds travel through the respiratory chain to ultimately form water from dioxygen reduction. Moreover, anaerobic fermentation, photosynthesis and nitrogen fixation produces and releases free gaseous H2. The life-supporting oxygen has three sources, atmosphere, water and carbon dioxide. ...Download file to see next pagesRead More

Business Cycles and Concepts

...? Unemployment in South Africa Lecturer The rate of unemployment can be defined by either the ILO harmonized definition, the national definition, or the OECD harmonized definition. The unemployment rate as per the OECD harmonized is the number of unemployed people as a percentage of workforce force (the total number of employed persons and those unemployed). The International Labor Organization defines unemployment as the number of workers who are currently not working, although are willing and able to work for the available pay, have actively searched for work, and are currently available to work (Timmons, 2008). Hence, the rate of unemployment can be referred to as the number of people who are actively looking for work divided... Unemploymen...

Business Cycles

...Is policy makers' concern relating to business cycles justified Give reasons for your answer. What policies have traditionally been used to damp downthese cycles Business cycles, also known as economic cycles, consist of periodic fluctuations in economic activity concerning its long-term growth trend. A typical business cycle involves periodical shifts between rapid growth of productivity, recovery and prosperity, and periods of stagnation or decline. These fluctuations are usually measured by the real gross domestic product (GDP). One of the policy makers' main roles is to smooth out the business cycle and to reduce its fluctuations...

Growth and Business Cycles

...Growth and Business Cycles In discussing the future of business cycles in the United s, I am personally rather an optimist. This is primly due to the fact that I believe in today's world people for the most part are sort of helpless spenders. More money is being made by more people in various different fashions, and that figure does not seem to be slowing down in any way. I think that recessions which be much shorter and fewer of them at that, and this is mainly again due to the spending habits of the public. High priced luxury items seem to be the craze of even the average person, seemingly regardless of their income. In regards to which major trend I think will have the biggest impact on the business cycle, I believe... the...

Stock Market Cycles

...Street Address ST ZIP e-mail phone fax What Drives Stock Market Cycles Many would argue that what drives the stock market is what is going on in the news or at the White House. This is only minutely correct in relation to all the other factors that drive the market. Yes, the stock market reacts to announcements with fluctuations in the market that are short lived. The announcement that President Bill Clinton was going to be impeached, Scooter Libby's indictment, and in the aftermath of Hurricane Katrina the stock market responded by losing ground. But, in the above mentioned cases the stock market quickly recovered and made gains. Although the political world affects the stock market in the short term the market...

Property Cycles - UK Experience

...Property Cycles – UK Experience Part One Rationale and Aim of the Research Current research is based on the property market of UK especially regarding the so-called property cycles and their effects on local economy. The particular issue has been extensively examined in the literature and it has been noticed that ‘the housing market, which has been particularly cyclically volatile in the past 30 years, has contributed to cycles in consumption through its impact on housing wealth; increased house prices increase the value of assets held, and impact on consumption, making the economy more cyclical’ (Barrell et al., 2003, 53). The above described cycles have been proved to...

Biogeochemical Cycles

...Biogeochemical Cycles: Hydrologic Cycle Hydrologic Cycle, also known as the water cycle, refers to constant movement of water on, above and below thesurface of the Earth and this process has a vital role in the conservation of Earth’s water. In the process of hydrological cycle, water is in constant motion cycling from ocean to sky to earth and the pathway of this cycle makes this constant motion possible. Precipitation, which is a familiar part of the hydrologic cycle, falls on the land surface and then enters into various pathways of the hydrologic cycle. Therefore, the...

...A few years ago I underwent a group experience that has had a great impact on me since then. I was 16 then and wanted to be a cheerleader. I tried out and made the team. Little did I know that I was about to receive a learning experience the likes of which I had never expected. The cheerleading team was formed at the beginning of the school year. It was a couple of weeks after school had started. The veteran cheerleaders explained to us, those who came and tried out for the team, what they are looking for and then we all tried out. Then those of us who got in were explained what were expected of, and so our group was formed. But after I got into the team, I learned that being in it wasnt so glamorous and exciting as Id previously... few years ...

How do humans interfere with biogeochemical cycles

...The Nitrogen Cycle The nitrogen cycle is the process and the movement of nitrogen through the ecosystem. Nitrogen is an important constituent of theatmosphere and makes up 79% of the Earth’s atmosphere ( During the nitrogen cycle, nitrogen in the air present in the form of nitrous and nitric oxide, travels to the earth as nitric acid, or acid rain. The process of nitrogen fixation involves nitrogen fixing bacteria found in the roots of certain plants and these bacteria are able to convert atmospheric nitrogen into organic molecules and proteins (Csuros, 1999:61). This nitrogen then travels to animals and humans when the plants are eaten, and is excreted as urine, which contains ammonia. Ammonia is poisonous... , but...

Macro : Business Cycles

...Business Cycles Q1. Business cycle is a major economic phenomenon that poses challenges and problems to economists in their attempt to stabilize the economic growth rate and stability. Each economy faces the changes in economic cycles that results in instability and brings different economic problems. During the recession for instance, the rate of unemployment rises and the inflation rate declines (Stock and Watson 56). The period is characterized by low level of investments and decline in the GDP. Considering the data of US in 2012, US can be said to be in the expansion cycle. Expansion cycle is the upward movement from the recession and the...
