    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.  The four important biogeochemical cycles are water cycle, nitrogen cycle, carbon cycle and oxygen cycle.
