Carbon Fixation
- Carbon is present in the atmosphere in the form of carbon dioxide gas
- Carbon is taken out of the atmosphere by plants to be used in photosynthesis
- Plants are autotrophs
- Autotrophs use light energy to convert carbon dioxide from the environment into carbon compounds, such as:
- Carbohydrates
- Lipids
- Amino acids
- This reduces the amount of carbon present in the atmosphere and stores it in the tissues of plants
