उत्तर
If there were no air on Earth, life would not be possible. Humans, animals and plants need air to live. We need oxygen from the air for respiration, and plants need carbon dioxide from the air for photosynthesis. Air is also necessary for burning and for many natural processes.
Without air, there would be no breathing, no photosynthesis, and no fire, and living organisms would not survive. Therefore, air is an essential natural resource for life on Earth.
