Carbon Cycle
- In the atmosphere, carbon is attached to oxygen to form carbon dioxide (CO2). Through the process of photosynthesis, CO2 is used to produce food for plants.
- Through food chains, carbon in plants moves to the herbivore animals. Carnivores get their carbon from other animals.
- Carbon moves from plants and animals to soils when they die.
- Animals release CO2 during respiration.
- Carbon moves from fossil fuels to the atmosphere when fuels are burned. The oceans, and other bodies of water, absorb some carbon from the atmosphere. Over long time scales, carbon is removed from seawater when the shells and ....
