Answer:

Oxygen Supply

Half of the world's oxygen is produced via phytoplankton photosynthesis. The other half is produced via photosynthesis on land by trees, shrubs, grasses, and other plants. As green plants die and fall to the ground or sink to the ocean floor, a small fraction of their organic carbon is buried.
