define biochemical cycle.

Hi,

The cyclic flow of nutrients between non living environment and living organisms is known as biogeochemical cycles. It is the process of transfer and circulation of the essential chemical nutrients such as Oxygen, Hydrogen, Carbon and Nitrogen in a biosphere.In biogeochemical cycle nutrients or chemical molecules rotate within the biotic and abiotic spheres of earth. In this cycle both biological (biotic), geological (abiotic) and chemical (nutrients) components are interconnected to each other.
