They drift through the ocean; zooplankton eat phytoplankton, which transfers the energy phytoplankton create with photosynthesis to the next level of the fish food chain.

What is zooplankton in the food chain?

Zooplankton are small, aquatic microorganisms in the water column that include crustaceans, rotifers, open water insect larvae and aquatic mites. The zooplankton community is composed of both primary consumers, which eat free-floating algae, and secondary consumers, which feed on other zooplankton.

What do crabs eat in the sea?

They are carnivores, which means they like to eat meat, so they catch fish, other crabs, worms, squids, starfish, and snails. They hunt along the sea floor for animals that are partly covered by sand. Dungeness crabs will also eat fish eggs, and will even eat other Dungeness crabs!
