Define biogeochemical cycle. Describe carbon cycle.

A biogeochemical cycle is a pathway by which essential chemical substances move through the biotic and abiotic components of Earth. Nitrogen, oxygen, phosphorous, Sulphur, water cycles are some important biogeochemical cycles.

CARBON CYCLE- The carbon cyle is the process in which carbon travels from the atmosphere into the organism and the Earth and then back into the atmosphere. Plants take carbon dioxide form the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.
