 Carbon cycle

Carbon is exchanged among atmospheric, oceanic, biological and geological reservoirs. A model that only redistributes carbon among closed reservoirs cannot permanently remove its total excess burden.

The carbon cycle is the process through which carbon is exchanged between the Earth's atmosphere, land, oceans, and living organisms. It is a crucial component of the Earth's biosphere, facilitating the flow of carbon in various forms, such as carbon dioxide (CO2), organic compounds, and carbonates.
