Biochemical Cycles

A biochemical cycle refers to the natural cycle of the earth through which a chemical substance or matter moves through the biotic and abiotic components of the earth. These components always interact with each other and form a stable system in the biosphere.

There are four main biogeochemical cycles

The Water Cycle
The Nitrogen Cycle
The Carbon Cycle
The Oxygen Cycle
