Biogeochemical Cycles

Biogeochemical Cycles
(Cycles in Ecosystem)
There is a constant recycling of essential nutrients within the biosphere from environment to organism and back to environment. Since the path of recycling involves living organism (bio), soil (geo) and chemical reaction these cycles or circular paths are called biogeochemical cycles. The elements which are recycled include Carbon, Hydrogen, Oxygen, Nitrogen, Phosphate and many others. Carbon, Hydrogen and Oxygen are closely associated with each other. Therefore, they form a single carbo, hydrogen, oxygen cycle, but the nitrogen and phosphorus form independent cycles.
