Are tuna and lancent fish secondary consumers?

Yes, they are secondary consumers. Tuna and lancet fish are both carnivores and they feed on smaller animals. Tuna are typically found in the open ocean and eat fish, squid, and other marine animals. Lancet fish are small fish that are often found in coastal waters and eat zooplankton and other small invertebrates. Since they feed on other consumers, which in turn feed on producers, they are secondary consumers.
