Question

How is the balance between oxygen and carbon dioxide 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.

Hope it helps!!

Answer 2

humans and animals take oxygen to respire and leave out carbon dioxide as resultant. plants take in carbon dioxide to photosynthesis, and leave out oxygen as resultant, however plants take oxygen to respire it does not make much difference.cutting down of trees can make this balance brake.
