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.
So let's start with oxygen which for the most part exists as molecular oxygen OÂ² which is O=O. Oxygen makes up about 21% of the air we breathe. It can be produced by photosynthesis using sunlight, water and Carbon Dioxide through a number of processes for a different post. Oxygen is used in our bodies with glucose to produce energy and water. This energy is then used throughout the body where needed.
