Plants and Air - Carbon Dioxide Oxygen Cycle
Carbon Dioxide-Oxygen Cycle
- Plants use carbon dioxide from the atmosphere during photosynthesis.
- Plants release oxygen into the atmosphere during photosynthesis.
- Animals, including humans, need oxygen to breathe and inhale oxygen from the atmosphere.
- Animals exhale carbon dioxide.
- Plants use the carbon dioxide released by animals to photosynthesize and release oxygen, which is called the carbon dioxide-oxygen cycle.
