In the carbon cycleDescribes how carbon moves around the environment. It is an example of a biogeochemical cycle. See also carbon flux. In recent years the carbon cycle has been studied intensively in order to... More, the transfer of carbon from one ‘pool’ to another. Scientists try to work out the rate of flux, i.e. how much carbon is transferred in a given time period, such a per year. Carbon fluxes along pathways generally vary, for example plants take up more carbon from the atmosphere during the daytime than at night, and during the growing season.
