Who Gives More Oxygen?
The ocean produces approximately half of the Earth's oxygen. While trees are vital oxygen producers, microscopic phytoplankton in the ocean's surface layer are responsible for a greater quantity. These tiny organisms, including species like Prochlorococcus, are incredibly efficient at photosynthesis and collectively produce significantly more oxygen than even the largest terrestrial plants.

Terrestrial Oxygen Production
While trees and other plants are essential for oxygen production, their contribution is roughly equal to that of the ocean. Factors influencing oxygen production by trees include leaf area and the rate of photosynthesis. Source: World Economic Forum

- Relative Contribution: Although individual trees might have high oxygen production rates, the cumulative effect of oceanic phytoplankton surpasses that of terrestrial plants. Source: Smithsonian Ocean
In summary, while both the ocean and terrestrial plants are vital for oxygen production, the ocean is responsible for approximately half of the total global oxygen production, primarily due to the massive contribution of microscopic phytoplankton.
