It is estimated that about 50% of the world's oxygen is produced via phytoplankton photosynthesis. The rest is produced via photosynthesis on land by plants. Furthermore, phytoplankton photosynthesis has controlled the atmospheric CO 2 / O 2 balance since the early Precambrian Eon.
Phytoplankton absorb energy from the sun (photosynthesis) and nutrients from the water to produce their own food. An estimated 50 percent to 85 percent of Earthâs oxygen is produced by this type of plankton photosynthesis with the remaining percent produced by land plant photosynthesis.
