Process of recycling carbon atoms on Earth has several step:
- Carbon is released into the atmosphere as carbon dioxide from respiration.
- Producers (plants) absorb carbon dioxide and make carbohydrates in photosynthesis.
- Consumers (animals) eat producers and intake carbohydrates.
- After the death of both producers and consumers, detritus feeders (bacteria and fungi) eat dead organisms and carbon is released into the environment.
