Although it is only one micron in length, this microbe is responsible for an estimated 20% of the oxygen in our atmosphere. The oxygen produced by phytoplankton and forests is roughly balanced by the oxygen consumed during respiration—by animals, plants, and microbes during decomposition.
Underwater Oxygen Factories: The Microscopic Powerhouses Driving Earth's Atmosphere
These marine photosynthesizers dominate planetary oxygen production, driving the air we breathe in a way that land-based ecosystems cannot match. Land Plants: Vital But Outnumbered While the question what makes the most oxygen on earth is settled by the oceans, terrestrial plants play an indispensable supporting role.
Protecting the health of our oceans is therefore synonymous with protecting the air we breathe. These tiny, free-floating algae perform nearly half of the world’s photosynthesis.

This cycle ensures that the atmosphere remains consistent, even as individual organisms come and go, highlighting the resilience of the planetary system. Prochlorococcus is the most abundant photosynthetic organism on the planet.
