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?we

The answer is secondary consumer.

A trophic level of an organism shows its position
in a food chain:

1. Producers, such as plants and algae, produce
their own food and thus are the base of every food chain.

2. Primary consumers eat producers. They are
herbivores that eat plants.

3. Secondary consumers eat primary consumers.
They eat herbivores, so they are carnivores or omnivores.. 

  1. The highest level is tertiary consumers that eat secondary

consumers


According to this, and knowing than yellowfin tuna eat smaller herbivorous fish, it can be concluded that it belongs to the secondary consumers.
