▼

- Photosynthesis absorbs CO2 from the atmosphere and converts it into organic carbon in plants using sunlight.
- Plant respiration releases some of that stored carbon back into the atmosphere as CO2.
- Animal respiration also releases CO2 into the atmosphere after animals consume plants or other animals.
- Decay organisms break down dead organisms and waste products, releasing CO2 through decomposition.
- Root respiration by plant roots contributes additional CO2 to the soil and atmosphere.
- Fossils and fossil fuels store ancient organic carbon; when burned (e.g., in autos and factories), they release large amounts of CO2.
- Auto and factory emissions directly add CO2 to the atmosphere from burning fossil fuels.
- The cycle continues as atmospheric CO2 is again absorbed by plants via photosynthesis.
