Yellowfin tuna, or Thunnus albacores, are large sport fish that are found in tropical and subtropical waters around the world. T
hey 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

This shows they are not tertiary consumers, as tertiary consumers are at the top of the food chain.</span>
