Trees maintain the balance between gases in the air, removing carbon dioxide from the air and releasing oxygen. true or false

The given statement is True.

By the process of photosynthesis, plants help in maintaining the balance between gases in the air.

In the light reaction of photosynthesis, plants consume water and solar energy to produce ATP and NADPH. Oxygen is released as the by-product of the reaction.

In dark reaction, they consume ATP, NADPH and carbon dioxide to fix carbon in sugars or food.  

Thus, plants remove carbon dioxide from the air and release oxygen into it.
