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?

Yellowfin tuna can be considered to be in the secondary consumer trophic level. The first trophic level, called producers, are the organisms that can make their own food. The second level, called primary consumers, are herbivores who consume producers. The next level, called secondary consumers, consume herbivores. Since yellowfin tuna eats herbivorous fish, the former is a secondary consumer.
