Most phytoplankton serves as food for zooplankton, but some is carried below the light zone. After death, this phytoplankton undergoes chemical mineralization, bacterial breakdown, or transformation into sediments. Phytoplankton production usually is greatest from 5 to 10 metres (16 to 33 feet) below the surface of the water.

Selective grazing by zooplankton is an important factor affecting the structure of phytoplankton communities. The marine food chain starts with microscopic plants called phytoplankton, which typically float close to the surface where there is sunlight for photosynthesis.

Phytoplankton: Zooplankton: Definition: Phytoplankton is a group of free-floating microalgae that drifts with the water current and forms an important part of the ocean, sea, and freshwater ecosystems. Zooplankton is a group of small and floating organisms that form most of the heterotrophic animals in oceanic environments. Terms Phytoplankton is plant-like aquatic microorganisms whereas zooplankton is aquatic animal-like organisms and the larval stages of other life forms. Examples of phytoplankton are diatoms, dinoflagellates, blue-green algae, and cyanobacteria while zooplankton is crustaceans-like krill, holoplankton, meroplankton, protozoans, and worms. No specific FCOs for phytoplankton, zooplankton, and benthos exist. However, FCOs call for balancing predator abundance with prey-fish production, which is a function of plankton and benthos production. The Great Lakes National Program Office (GLNPO) of the U.S. Environmental Protection Agency has conducted regular surveillance monitoring of Lake Zooplankton are generally larger than phytoplankton, mostly still microscopic but some can be seen with the naked eye.
