CO2 and the soil but mostly CO2
p.s.
dont listen to raredawn. the carbon source of organisms depends on the organisms metabolism. there are bacteria that breath sulfer instead of oxygen or CO2 but there carbon source is from their enviroment such as from the ground or other decomposing organisms. god i hate stupid people that just blurt out whatever they are thinking and think they are right.
