Photosynthesis requires carbon dioxide and water; when the chlorophyll in these organisms absorbs sunlight, it splits water molecules. Its sheer numbers and efficiency in nutrient-poor waters make it the undisputed leader in the race to produce breathable air.
Microbial Insights: Securing Earth's Oxygen Future Through Marine Photosynthesizers
How Photosynthesis Powers the Atmosphere The process behind this oxygen generation is straightforward yet profound. These marine photosynthesizers dominate planetary oxygen production, driving the air we breathe in a way that land-based ecosystems cannot match.
However, their total biomass and photosynthetic capacity are limited compared to the volume of microscopic life in the sea, meaning they are essential partners rather than the primary suppliers. Although it is only one micron in length, this microbe is responsible for an estimated 20% of the oxygen in our atmosphere.
