Describe at least two ways that carbon can get from land plant to the atmosphere ?

Carbon moves from living things such as plants to the atmosphere through the process of respiration. During respiration plants utilize oxygen and glucose to obtain energy resulting in the release of carbon dioxide, water and ATP. The carbon dioxide is then released to the atmosphere. The second way in which carbon dioxide is released to the atmosphere from plants is when the plants die, they are decomposed and carbon atoms are returned to the atmosphere.
