Life on our planet is made up of an incredible variety of carbon molecules, and, in essence, life processes are carbon chemistry. Conversely, the carbon cycle, which can be viewed as the movement of carbon atoms through various places of storage on Earth, called reservoirs, is intimately tied to life processes.xamples of reservoirs are the ocean, the atmosphere, the biosphere, the soil carbon, the carbonate sediments, and the organic carbon sediments.. The fluxes between them describe the rate at which atoms move from one reservoir into another.
