How did the carbon atom get from land animals back to the atmosphere? Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. ...
