Here's how:
* Phytoplankton: These tiny marine algae are responsible for a significant portion of Earth's oxygen production through photosynthesis. They use sunlight, carbon dioxide (CO2), and water to create energy and release oxygen as a byproduct.
* Plants: Through photosynthesis, land plants also absorb CO2 and release oxygen into the atmosphere.
While both phytoplankton and plants produce oxygen, phytoplankton are estimated to produce about half of the oxygen we breathe. This highlights their critical role in maintaining Earth's atmosphere and supporting life.
