The correct option is C Nutrients in an ecosystem

Biogeochemical cycle is a pathway by which a chemical substance moves through both biotic and abiotic compartments of earth. The circulation of chemical nutrients like carbon, oxygen, nitrogen, phosphorus, calcium and water, etc., through the biological and physical world are known as biogeochemical cycles. In effect, the element is recycled, although in some cycles there may be places where the element is accumulated or held for a long period of time.
