what is phytoplankton?

Phytoplankton are small, photosynthetic organisms that drift in aquatic environments, such as oceans, lakes, and rivers.

These organisms are of great importance for the origin of life. Acting as the foundation of the food chain in numerous marine and freshwater ecosystems, these small, single-celled algae play a vital role. Beyond their impact on the food chain, phytoplankton also contribute significantly to global carbon cycle. 

By absorbing carbon dioxide from the atmosphere and releasing oxygen through photosynthesis, they shape the delicate balance of our planet's ecosystems. Scientists estimate that at least 50 percent of the oxygen in our atmosphere has been produced by phytoplankton.
