Plankton is as important as the land plants. Phytoplankton produces lots of oxygen through photosynthesis which is the lifeline for the marine species. The phytoplankton assemblage of Lake Kinneret is dominated by dinoflagellates. Secondary phytoplankton biomass contributors are cyanobacteria, chlorophytes, and diatoms, whereas cryptophytes are Se hela listan på aquaculturealliance.org Phytoplankton typically range in size from 0.002 mm to 1 mm and include diatoms, dinoflagellates, Radiolaria, Ciliata and Cyanobacteria (better known as ‘blue-green algae’). Phytoplankton produce more oxygen than all plant life on earth and are vital in maintaining the earth’s atmosphere.
