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.
Is a small fish a producer or consumer?
Secondary consumers
make up the third level of the food chain. Secondary consumers feed on smaller, plant-eating animals (primary consumers). Examples of secondary consumers include bluegill, small fish, crayfish and frogs.
Is a fish a omnivore?
The majority of marine fish are omnivorous
, which means they need to eat both meat- and plant-based foods. One easy option for omnivorous eaters is commercial fish food, such as flakes or pellets.
Is a fish a tertiary consumer?
Tertiary consumers in marine environments include larger fish such as tuna, barracuda and groupers, seals and sea lions, jellyfish, dolphins, moray eels, turtles, sharks and whales
—some of which are apex predators, such as the great white or tiger sharks and orca whales.
Are fishes secondary consumer?
Fish, jellyfish and crustaceans are common secondary consumers
, although basking sharks and some whales also feed on the zooplankton.

Are large fish primary consumers?
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 …
Are all fish carnivorous?

the majority of fish we eat are carnivorous

Why are fish omnivores?

Why fish is a primary 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.

Are fish decomposers?
The food-chain includes the producer, primary consumer, secondary consumer and decomposers. Diatoms are a major group of algae, and are among the most common types of phytoplankton so are the producers, crustacean belongs to primary consumer,
fish is secondary consumer
, seal is tertiary and bacteria are decomposers.
What is the primary consumer?
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.
What are examples of 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.
