4.9 Carbon Cycle

• C02+H20 are combined in photosynthesis using light energy.
• Light energy is trapped and used to form organic molecules such as glucose.
• The C02 comes from the atmosphere which makes 0.03% of the atmosphere.
• Photosynthesis is responsible for reducing the atmospheric C02.
• The passage of carbon through the various trophic level we have identified the producer
• The primary consumer takes in the carbon from the producer
