Question

Why does the percentage of gases like oxygen, nitrogen, and carbon dioxide remain almost the same in the atmosphere?

Answer 1

1. The gases like oxygen, nitrogen, and carbon dioxide remain almost the same in the atmosphere with the help of the biochemical cycle.
2. The interaction of abiotic and biotic components maintains the amount of these gases in the atmosphere.
3. . Cycling of these gases maintains consistency of these gases.
4. These are taken up and released by almost every living organism and thus their concentration in the atmosphere is maintained.
5. The biochemical cycles are nitrogen cycle, water cycle, carbon cycle, etc.
