Download file to see previous pages The biosphere provides a room where a cycle of biological process like decomposition, nitrogen fixing, photosynthesis of plants and respiration takes place. The ingredients also cycle in a way that they the biosphere allows the living things to take and also return them to the other spheres in a pragmatic way ( Smil &Vaclav 23-58). There are several factors that determine the biosphere which include; water, shelter, light and nutrients. Climatic conditions that vary from different places on the earth also influence the biosphere in a big way. These factors influence the cycles that take place upon the earth like the oxygen cycle, nitrogen cycle, geochemical cycles, biochemical cycle and the photosynthesis process. These processes ensure there is life on earth, for instance, when plants release the oxygen and the animals breathe in oxygen and release back the carbon dioxide that is used for photosynthesis. As a result of the biosphere cycles and process, the earth has not been altered and therefore provide a friendly environment for all living things ( Jorgensen, Sven and Brian 3-20). Oxygen Cycle Its the biochemical process that shows the movement of oxygen from the atmosphere, lithosphere and hydrosphere which is done through the process of photosynthesis ( Alcamo & I E 234-260). As the hydrologic cycle enables movement of water from the sky down to the earth, oxygen also is cycled in a certain pattern in the environment. In the process of photosynthesis, plants use the sunlight energy to convert carbon dioxide, then water into carbohydrates and oxygen. Plants play integral key role in the oxygen cycle because they breathe in carbon dioxide and breathe out oxygen; photosynthesis includes plants that grow in the land areas as well as the water and oceans. There is also a small percentage of oxygen that is produced from photolysis when energy through radiation breaks down the water in the atmosphere and nitrogen oxide into atomic elements, including more components hence leaving some oxygen in the air. Animals breathe in the oxygen produced from the plants in the process of photosynthesis and breath out carbon dioxide through the process of respiration. The carbon dioxide breathed out by animals is therefore released into the atmosphere hence forming the continuous cycle of oxygen. In the process, plants during the day, they use the oxygen to break down the carbohydrates; same as the animals break down the carbohydrates during respiration. For the rate of metabolism to be maintained, plants do absorb oxygen from the air and give carbon dioxide to the air like the animals do. Plants produce a lot of oxygen during the day as compared to the night because of availability of sunlight, although in times whereby plants consume a lot of oxygen during the night, can lead to low oxygen levels in marine areas. Carbon dioxide is also released into the atmosphere when organism decay and bacteria consume oxygen through decay mechanism and process. The cycling process of oxygen also takes a place between the biosphere and lithosphere when the marine biosphere creates calcium carbonate element that contains oxygen. As ( Harman& Rebecca 50-100) points out, the biosphere extracts nutrients from the rock elements which enables a release of oxygen into the atmosphere and that the ozone layer has been created in the stratosphere due to the oxygen that is ...Download file to see next pagesRead More

...?Geography: Hydrosphere, Biosphere & Lithosphere Describe the paths of water through the hydrologic cycle. Explain the processes and the energy gains and losses involved in the changes of water between its 3 states. Operationally, we often most concerned with water does when it reaches the solid earth, both on the surface and in the sub-surface. Explain the relationship between the saturated zone, the water table, a ground water well and the cone of depression, all within the sub-surface. In the hydrological cycle, the water circulates between the oceans, the atmosphere and the continents. The water can exist in any of the three states during the transportation, i.e. as vapor expressed as...

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...

Design Patterns

...?DESIGN PATTERNS Design Patterns Affiliation The Observer Pattern The Observer is a well-known design pattern in which a listof objects depending on an object (which is also acknowledged as a subject) is maintained. In this scenario, the observer is the object which depends on the subject. Additionally, this subject automatically informs all the objects (observers) regarding any changes made to the state. In order to inform other objects or observers regarding something attractive taking place, a subject distributes an announcement or message to the observers that exist on the list of the subject. This notification can encompass particular information and facts regarding...

Our Biosphere, Our Future

...Our Biosphere, Our Future What would the future be like for the next generations if we do not change the way we treat our planet now? A concern for future generations should motive us against any future encroachments against nature. To examine this, we will specify the problem, offer solutions, consider ethics, and propose measures. The central problem is the way we abuse nature will use up her ability to bounce back. Future generations may not be able to enjoy opportunity for healthy lives simply because we are not using our planets resources wisely. Without clean water, clean air, clean food, and an environment free of toxins, the likelihood that people will not be as healthy is a given. This problem is no...

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...

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 pathway of the...

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...

Biogeochemical Cycles

...Biogeochemical cycles A biogeochemical cycle is a cyclical pathway through which all nutrients stream in to the living components from the nonliving and then back to them. Bio means living, geo means rocks and soil and chemical means the involved processes. Out of the gaseous and sedimentary cycles, the two basic types, the former is global. The reason being its major nutrient pools are the atmosphere and the oceans, hence making it so. “The three most important gases for life are nitrogen, oxygen and carbon dioxide. They are present in steady quantities of 78, 21 and 0.03 percents respectively, in atmosphere” (Smith, pp. 475). (Figure: Smith, pp.475) A nitrogen...
