Copepods feed on dinoflagellates and incorporate this energy into their own tissues.What place do Sharks hold in the aquatic food chain?Sharks play an important role at all tropic levels of the ocean ecosystem from scavengers to super-predators. Scavengers prey upon dead or dying animals, super predators help to control populations and maintain prey species diversity by concentrating on the most available species.
