How do plants and animals in help each other in the exchange of gases in the atmosphere?

  1. Plants make their own food by the process of photosynthesis. In this process, they take carbon dioxide and give out oxygen.
  2. Both animals and plants use oxygen from the air during respiration and release carbon dioxide gas in air. This released carbon dioxide again used by plants for photosynthesis.
  3. This shows plants and animals help each other in the exchange of gases in the atmosphere.
