Question

Write about biogeochemical cycles in the environment.

Answer 1

The cycling of chemicals between the biological and the geological world is called biogeochemical cycle. The biotic and abiotic components of the biosphere constantly interact through biogeochemical cycles. During these interactions, there is a transfer of nutrients between living organisms and the non-living environment.
 

Answer 2

In geography and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. There are biogeochemical cycles for carbon, oxygen, nitrogen, phosphorus, sulfur, and water; and there are human-induced cycles such as those for mercury and atrazine. In some cycles there are reservoirs where a substance remains for a long period of time (such as an ocean or lake for water)
