Importance of air to plants and animals
Do you know why air is important to all plants and animals?
When human beings, animals birds, and plants inhale air, they also take in oxygen.
When they exhale, they give out carbon dioxide.
Plants take in carbon dioxide and give out oxygen during the process of photosynthesis/preparing food.
