Its A!..
Quite a trick question but all the other answers seem to be wrong!

So i think its A cuz plants get CO2 by photosynthesis and animals eat plants and use the food they ate and when they die in a 10000000 years they get combusted to give out CO2.. ::)

Carbon compounds in green plants are transfered to animals during nutrition ( when the animals eat the plants they take in the carbon compounds such as carbohydarates)
Carbon compounds in animals are transfered to air by excretion of Carbondioxide by the lungs (exhalation)
