This splitting releases oxygen as a waste product, which is then expelled into the water and eventually into the air. Although it is only one micron in length, this microbe is responsible for an estimated 20% of the oxygen in our atmosphere.

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. Additionally, ocean acidification, driven by absorbed carbon dioxide, can weaken these microscopic organisms.
Forests, grasslands, and urban trees contribute roughly 28% of the world's oxygen. In reality, the Earth maintains a stable equilibrium.

Unlike dense forests, this biological activity is distributed across the vast, open waters, creating a continuous global output that is difficult to visualize but absolutely critical for life on Earth. This cycle ensures that the atmosphere remains consistent, even as individual organisms come and go, highlighting the resilience of the planetary system.
