Food Webs
Here is a food chain of some of the organisms in the Chesapeake Bay estuary. The food chain starts with phytoplankton converting sunlight and nutrients into living tissue. Phytoplankton are eaten by copepods, which are members of the microscopic animal community called zooplankton. Copepods are then eaten by bay anchovies, which are eaten by large fish such as bluefish and striped bass. These large fish can then be caught and eaten by humans.
