Carbon Dioxide is removed from the environment by green plants for photosynthesis it is also put into the air by respiration by animals and green plants. The carbon from the CO2 is used to make carbohydrates, fats and proteins.
Animals eat green plants and thus build carbon into their bodies.
When animals or plants die, microorganisms release the CO2 into the air
For a plant to decompose, microorganisms digest the materials.
Microorganisms digest materials faster when there is plenty of oxygen
Importance of Carbon: - It is the main constituent of all living cells
- Carbon can form fats, carbs, nucleic acids and proteins
- Component of fuel
- Used in nanotubes for computers
