Balance of oxygen and carbon dioxide in the air


BALANCE OF OXYGEN AND CARBON DIOXIDE IN THE AIR


•           The balance of oxygen and carbon dioxide in the atmosphere is maintained through respiration in plants and animals and by photosynthesis in plants.

•           Plants produce oxygen during photosynthesis and utilize oxygen during respiration.

•           They produce much more oxygen during photosynthesis than they consume.

•           This is how the oxygen consumed by plants and to a large extent by animals is replenished in the air through photosynthesis.
