Question

Yellowfin tuna, or Thunnus albacores, are large sport fish that are found in tropical and subtropical waters around the world. They typically school under objects such as boats or patches of driftwood for protection from predators. Schooling under these structures also provides yellowfin tuna with easy access to a food source such as smaller herbivorous fish that may be foraging for food around the structures. Which trophic level does yellowfin tuna fill in a food chain? producer primary consumer secondary consumer tertiary consumer

Answer 1

The answer is secondary consumer.

Secondary consumers are organisms in the food chain that consume the primary consumers. They are eaten by tertiary consumers.

Rationalization

Tuna fish consumes small herbivores fishes. The herbivores fishes are primary consumers as they feed on producers.

It is consumed by tertiary consumers like bigger fishes. So it is a secondary consumer in the food chain.

It is not a producer as it does not synthesize its own food.

Answer 2

Yellowfin tuna is a SECONDARY CONSUMER.

consumers are the organism that eat other organisms while secondary consumers are the animals that eat primary consumers. there are further two groups of secondary consumers; one is carnivores that eat meat  and others are omnivores that eat  plant and animals.

as yellowfin tuna is a CARNIVORE it usually feed on squids,  lobster and other tuna.
