The biogeochemical cycle is defined as the natural pathway, in which essential elements like nitrogen, oxygen, can carbon are circulated from non-living to living components.
The primary difference between the oxygen, nitrogen, and carbon cycle is the major reservoir, and the pathway these cycles perform.
The nitrogen, carbon, and oxygen cycle differs as follows:
- The nitrogen cycle explains the circulation of nitrogen and nitrogenous compounds through biotic and abiotic components. The nitrogen is present in nitrite, ammonia, and nitrous oxide form. It is converted into nitrogen and is then utilized by plants and organisms.
- The oxygen cycle is the movement of oxygen between the atmosphere, lithosphere, and biosphere. The oxygen is released by plants and then is consumed by the animals and other organisms. Oxygen is released as free oxygen molecule.
- The carbon cycle is the complex cycle in which carbon is circulated through the biosphere, geosphere, atmosphere, hydrosphere, and pedosphere. Carbon is essential for the sustainability of living organisms. It can be circulated by burning fossil fuels, exhalation by animals, and decomposition of living matter.
Therefore, these biogeochemical cycles are essential and maintain the sustainability of living organisms. The cycles pathway and compounds are different in each cycle.
