Primary consumers in the ocean include zooplankton, small fish, and crustaceans. The secondary consumers are fish, coral, penguins, whales, and other species that eat the zooplankton.

sea star, also called starfish, any marine invertebrate of the class Asteroidea (phylum Echinodermata) having rays, or arms, surrounding an indistinct central disk.

A starfish is a tertiary consumer in the ocean ecosystem. Although starfish might look harmless, they are actually important predators in their…

Food webs describe who eats whom in an ecological community. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.

The primary consumer is an organism that eats a primary producer, which can include a zooplankton or snail in the ocean. The secondary consumer is an organism that eats a primary consumer, and includes fish species that feed on the zooplankton.

The dolphins are a tertiary consumer in this food chain as well, since they eat secondary consumers: the tuna and mackerel.

Members of the second trophic level generally are the herbivores that feed on the first trophic level, making them primary consumers. The third level of organisms are predators that feed on the primary consumers, earning them the name secondary consumers. Crappie exist on the third trophic level as carnivores.

The salt water food web begins with producers (plants, algae, phytoplankton) that create food from sunlight, and continues with primary consumers (zooplankton) that eat the producers, followed by secondary consumers (shrimp, crustaceans, small fish) that eat the primary consumers, then tertiary consumers (large …

Examples of secondary consumers: Carnivorous fish, seals, sea stars, whales, squid, some crabs ,lobsters etc. Some examples of tertiary consumers: Dolphins, sharks, killer whales, some sea birds etc. Apex predators: Some tertiary consumers are considered apex predators.

Fish, jellyfish and crustaceans are common secondary consumers, although basking sharks and some whales also feed on the zooplankton.

Primary consumers are those that consume the primary producers (plants). For example- rabbits consume grass. Secondary consumers are those that consume the primary consumers (herbivores). For example- Snakes that consumes rabbit.

The organisms that eat the producers are the primary consumers. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number.
