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.
