1. Producers take in carbon dioxide from the air during photosynthesis.
Carbon Dioxide-Oxygen Cycle
Producers take in carbon dioxide from the air during photosynthesis.

2. Plants use the carbon from carbon dioxide to make sugar and starches.
Carbon Dioxide-Oxygen Cycle
Plants use the carbon from carbon dioxide to make sugar and starches. +
(Glucose)
Carbon Dioxide + Water + light energy Sugar + Oxygen +Water

3. Carbon Dioxide-Oxygen Cycle
Plants release oxygen into the air as a waste product from photosynthesis.

4. Carbon Dioxide-Oxygen Cycle
Most consumers take in the oxygen released by producers and use it during respiration.

5. Carbon Dioxide-Oxygen Cycle
Also during respiration, a consumer eats the plants and breaks down these molecules into simpler molecules. +
Sugar + Oxygen   Carbon Dioxide + Water + Energy

6. Carbon Dioxide-Oxygen Cycle
Animals release the carbon dioxide they produce into the air as a waste product of respiration.
