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

n reach?Food chains show energy transfer between organisms. The size of a food chain can vary, yet there is a limit to the number of levels that a food chain can reach. Why is there a limit to the number of levels that a food chain can reach?

• Plants are not infinite

• Producers can only eat what is available

• Carnivores are too big to be eaten

• Energy is lost when you move up a trophic level
