In aquatic ecosystems fish are often the organisms at the top of the food chain. They are often the secondary and tertiary consumers. The producers in an aquatic ecosystem are algae and aquatic plants. These producers are consumed by the primary consumers, which are often small fish and aquatic macroinvertebrates.
Are fishes primary producers?
They are the first step in the food chain that provides the fish that humans consume. All primary producers, such as marine phytoplankton, use a variety of chemical pigments to capture the energy from sunlight.

Are fish considered secondary consumers?
Secondary consumers feed on smaller, plant-eating animals (primary consumers). Examples of secondary consumers include bluegill, small fish, crayfish and frogs. Top predators are at the top of the food chain. Top predators eat plants, primary consumers and/or secondary consumers.
Are fish tertiary consumers?
The larger fishes like tuna, barracuda, jellyfish, dolphins, seals, sea lions, turtles, sharks, and whales are tertiary consumers. They feed on the primary producers like phytoplankton and zooplankton, as well as secondary consumers like fish, jellyfish, as well as crustaceans.
What kind of consumer is a fish? – Related Questions
Is a fish a primary or secondary consumer?
Primary consumers are the animals in a food chain that feeds on plants, i.e., producers. In the figure, phytoplanktons are the producers that are consumed by small fishes, therefore small fishes are primary consumers. Large fishes are consuming primary consumers (small fishes), therefore they are secondary consumers.
Who are the primary consumers?
Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.
Who are the tertiary consumers?
Tertiary consumers are those that eats the secondary consumers (large predators). For example, owls that eat snakes.
What are some tertiary consumers?
Examples of Tertiary Consumers
- Humans. Humans are largely omnivorous.
- Big Cats like Lions and Tigers. Lions, tigers, leopards and other big cats are classed as tertiary consumers.
- Polar Bear.
- Secretary Bird.
- Crocodiles.
- Pythons and Boas.
- Other Examples of Marine Tertiary Consumers.
What is a tertiary 3 consumer?
A tertiary consumer is an animal that obtains its nutrition by eating primary consumers and secondary consumers. Usually tertiary consumers are carnivorous predators, although they may also be omnivores, which are animals that feed on both meat and plant material.
Is salmon a tertiary consumer?
Tertiary Consumers are animals which feed on primary and secondary consumers, but which in turn are prey to top predators. Examples of tertiary consumers are fish such as the Atlantic Salmon, and Kingfishers.
Is salmon a primary consumer?
Trophic levels with green algae as the primary producer, mollusks and snails are the primary consumers, and small fish (Slimy Sculpin) are the secondary consumers. The tertiary and apex consumer is Chinook salmon. One major factor that limits the number of steps in a food chain is energy.
Is shrimp a secondary consumer?
Some of this is plant stuff and some is animal stuff, so shrimp are omnivores. Sometimes they act as primary consumers (when they eat plants) and sometimes as secondary consumers (when they eat animals). Some scrape algae off of rocks to eat, and others eat dead tissue and bugs off of fish.
Is Dolphin a tertiary consumer?
The dolphins are a tertiary consumer in this food chain as well, since they eat secondary consumers: the tuna and mackerel.
Are sharks secondary consumers?
Smaller, less predatory sharks can also be considered secondary consumers because larger sharks, whales, or fish often hunt them. If there were no aquatic secondary consumers, then primary consumers would have no population regulation.
Is snake a tertiary consumer?
Snakes eat mice and other rodents, which classes them as secondary consumers; they also eat frogs and other snakes, which classifies them as tertiary consumers.
What type of consumer is a shark?
3. Some animals like sharks are 5th order consumers! Sharks eat tuna that eat mackerel that eat herring that eat copepods that eat diatoms.
What are 5 primary consumers in the ocean?
Phytoplankton and algae form the bases of aquatic food webs. 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.
Are crocodiles a consumer?
freshwater crocodile
Next in the food chain, green tree frogs eat cicadas, so green tree frogs are ‘second order’ consumers. Then, freshwater crocodiles eat frogs, so freshwater crocodiles are ‘third order’ consumers.
Are squid secondary consumers?
A squid is a tertiary consumer. The squid eats smaller animals like fish, shrimp and crabs. These animals feed on primary consumers, such as zooplankton. This makes the squid a tertiary consumer and one of the top organisms in its food chain.
