The process responsible for producing Earth's oxygen is photosynthesis, which occurs in plants, algae, and some bacteria. During photosynthesis, these organisms use sunlight, water, and carbon dioxide to produce oxygen and glucose. The oxygen released by photosynthesis is essential for supporting life on Earth.
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
