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

Text Solution

Verified by Experts

The composition of gases such as `O_(2), N_(2)` and `CO_(2)` remains same in atmosphere due to the process of biogeochemical cycles.
During these cycles occur the repeated circulation of biogenetic nutrients between abiotic and biotic components of the environment.
