Question

How do trees maintain a balance between oxygen and carbon dioxide in the environment ???

Answer 1

Plants produce oxygen during the process of photosynthesis. This is released into the air. ...

Animals use oxygen from the air for the process of respiration.

There is a balance between the excess oxygen given out by plants and the oxygen used by animals, so that the percentage of oxygen in dry air is always the same.

Answer 2

Plants take in Carbon Dioxide and water during the day in the presence of sunlight and chlorophyll to perform Photosynthesis. Oxygen is a by-product of photosynthesis which is released in the atmosphere.

Whereas at night, plants take in Oxygen and release Carbon Dioxide in the air therefore balancing Oxygen-Carbon Dioxide content in the atmosphere.

Hope this helps
