Itâs theelement that anchors all organic substances, fromfossil fuels to DNA. On Earth, carbon cycles throughthe land, ocean, atmosphere, and the Earthâs interiorin a major biogeochemical cycle (the circulation ofchemical components through the biosphere from orto the lithosphere, atmosphere, and hydrosphere).
The carbon cycle is the process in which carbon atoms are recycled over and over again on Earth. Carbon recycling takes place within Earth's biosphere and between living things and the nonliving environment. Since a continual supply of carbon is essential for all living organisms, the carbon cycle is the name given to the different processes that move carbon from one to another. The complete cycle is made up of sources that put carbon back into the environment and sinks that absorb and store carbon.
