State the different types of bio-geochemical cycles and explain the importance of those cycles.

Answer :

Most important biogeochemical cycles are the carbon cycle, nitrogen cycle, oxygen cycle, and the water cycle.


Biogeochemical cycles do many functions at ecosystem level and is ensure survival of various organisms including humans.


Some of the importance of biogeochemical cycles are given below:


I. Biogeochemical cycles change matter from one form to another. For example, humans use water in liquid form. Through the water cycle, water vapour is condensed to liquid and ice converted to liquid water.


II. Biogeochemical cycles transfer the molecules from one place to another. For example, another, the percentage of nitrogen is high in the atmosphere, but some of the atmospheric nitrogen is transferred to the soil through the nitrogen cycle.


III. Biogeochemical cycles link living organisms among themselves and with the non-living organisms. All organisms depend on one another and most especially, the biotic or living component and a biotic component of the ecosystem are linked by flow of nutrients.
