POOLS, FLUXES AND A WORD ABOUT UNITS In order to understand how carbon is cycled and how atmospheric CO2 will change in the future, scientists must carefully study the places in which carbon is stored (pools), how long it resides there, and processes that transfer it from one pool to another (fluxes). A food chain almost always begins with a green plant (producer) which is eaten by an animal (consumer). Living organisms are unique in that they extract energy from their environments via hundreds of coordinated, multistep, enzyme-mediated reactions.
