Question

Can ya tell me how is the balance between O2 and CO2 maintained? Mention one action that affect this balance??

Answer 1

Heya!!

Green plants give out oxygen during photosynthesis. 

This oxygen is used up when living things (including plants) respire, and carbon dioxide is released. 

This dual process ensures that the amount of oxygen and carbon dioxide in the atmosphere is always constant. 

This natural balance is affected when we cut down trees indiscriminately.
