Answer 2

Photosynthesis is the process through which oxygen, essential for survival of human beings, is replenished in nature.

When green plants make their food, they release oxygen and utilize C02 or carbon dioxide to perform photosynthesis.

The repeated cycle of release of oxygen in nature and consumption of carbon dioxide replenishes oxygen.
