Prochlorococcus is the most abundant photosynthetic organism on the planet. Photosynthesis requires carbon dioxide and water; when the chlorophyll in these organisms absorbs sunlight, it splits water molecules.
The Oxygen Powerhouse Phytoplankton and Earth's Breathable Air
This splitting releases oxygen as a waste product, which is then expelled into the water and eventually into the air. Forests, grasslands, and urban trees contribute roughly 28% of the world's oxygen.
The Balance of Carbon and Oxygen It is a common misconception that oxygen levels are dangerously low. The oxygen produced by phytoplankton and forests is roughly balanced by the oxygen consumed during respiration—by animals, plants, and microbes during decomposition.
How Prochlorococcus Phytoplankton Powers Earth's Oxygen Supply
Protecting the health of our oceans is therefore synonymous with protecting the air we breathe. Its sheer numbers and efficiency in nutrient-poor waters make it the undisputed leader in the race to produce breathable air.
