The Five Biogeochemical Cycles

The five most important biogeochemical cycles are the Oxogen cycle, Nitrogen cycle, Carbon cycle, Sulphur cycle and the Sedentary cycle. These five cycle’s can be classified into pools. Active pools are free flowing cycles controlled by life processes , such as photosynthesis. Storage pools are segregated bodies controlled by physical processes, such as volcanic eruptions or earthquakes. Sedentary Cycle Sulphur is mainly found in longterm storage pool within the crust and sediment of the earth. sulphur is released into the atmosphere by volcanic activity. This releases sulphur from the storage pool and into the active pool. Interesting note the fine particulate of free sulphur is a known to act as a condensation nuclei. Nitrogen is the most readily abundant element in our …show more content…
Co2 is released into the atmospheric active pool by physical processes such as combustion and volcanic activity. This new addition of Co2 will join the active pool and cycle through the ecosystem by way of life processes, such as Photosynthesis and the consumption of organic material by organisms. Carbon will return to the storage pool by water absorption and shellfish incorporation to the burial, decomposition and compression of organic material.

Oxygen is a fundamental element of the living biosphere. The Oxygen cycle is divided into two major loops, the H2o cycle and the Co2 cycle. In the H2o cycle, Oxygen atoms are bound with hydrogen to form molecular h20. This compound form, of oxygen and hydrogen is extremely stable and inert. Water has three naturally occurring states, liquid, solid and vapour.

The water cycle is a closed system driven by the free solar energy by way of evapotranspiration (E). The sun’s rays contact water and excite the molecules by way of latent heat transfer. This heat transfer is responsible for change in states from solid to liquid , from liquid to
