What are the secondary and tertiary consumers of oceans?

Hi, I was working on the ocean ecosystem. So far, I have the producers and primary done. I was wondering what are the secondary and tertiary consumers of oceans? Thanks so much.

    The ocean is home to a myriad of life forms. So, where to begin? Well..

    At the very bottom of the food chain are the producers, single-celled organisms that can make their own food. By using energy they absorb from sunlight, they take simple compounds from the water that they've absorbed through their cell walls and convert them into stored energy as sugar.

    Next in the chain are the animals that feed on phytoplankton. They are the primary consumers, or the first consumers in the food chain. Then come the organisms that feed on the primary consumers, known as secondary consumers.

    Finally, there are the tertiary consumers, the large fish and mammals that feed on the secondary consumers.

    Primary consumer-- Squid, any crustaceans, etc smaller fish like sardines

    Secondary consumer- Tuna, dolphines, bigger fish to eat the smaller, turtles

    Tertirary consumer- Sharks, killer whales, whales

    =)

    Secondary consumers are animals that eat the primary consumers, and tertiary ones eat the secondary.

    So, if the primary consumers are small zooplankton, the secondary ones would be small fish, like menhaden, which would in turn be eater by larger game fish, liked striped bass or tuna.
