Phytoplankton

Svenska: Växtplankton

Take a deep breath. Half of the oxygen you just breathed in came from microscopic phytoplankton - green algae, diatoms, cyanobacteria, and others. They only need sunlight and nutrients from the water to be able to take up carbon dioxide and make their food. These producers are at the bottom of the marine food chain.

Diatoms and other algae bloom in the Baltic Sea in the spring, after the ice breaks up. In the late summer, cyanobacteria may also bloom, which turns many regions of the sea to a bright green colour.
