Carbon Cycle

Carbon enters the atmosphere as carbon dioxide from breathing and burning. Carbon dioxide is absorbed by producers  to make oxygen in photosynthesis . Animals feed on the plants. Thus passing the carbon compounds along the food chain. Most of the carbon these animals consume however is exhaled as carbon dioxide. This is through the process of respiration. The animals and plants then eventually die. The dead organisms (dead animals and plants) are eaten by decomposer in the ground. The carbon that was in their bodies is then returned to the atmosphere as carbon dioxide. The decomposed plants and animals may then be available as fossil fuel. Those fossil fuels are burned in factories and releases carbon dioxide.
