Question

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

Answer 1

Atmosphere:

• The atmosphere is made up of different components.
• The major components of the atmosphere are Nitrogen $\left(\mathrm{N}\right)$, Oxygen $\left(\mathrm{O}\right)$, and Argon $\left(\mathrm{Ar}\right)$.

Percentage of gases:

• The percentage of gases such as oxygen, nitrogen, and carbon dioxide in the environment is maintained by their cyclic flow.
• The continual interplay between the biotic and abiotic components of the biosphere operates the oxygen, nitrogen, and carbon cycles, respectively.
• These interactions involve the exchange of matter and energy among the biosphere's various components.
• As a result, the levels of oxygen, nitrogen, and carbon dioxide in the atmosphere are always kept within a certain range.
