Yes, The carbon cycle is the \(\bf biogeochemical\) cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.

The word biogeochemical denotes that it is a cycle in which chemical elements and simple substances are transferred between `living systems and the environment.`
