Is a narwhal third level consumer?

Yes, a narwhal is a third-level consumer. Narwhals are a species of toothed whale that inhabit the Arctic waters around Greenland, Canada, and Russia. They primarily feed on fish, such as cod, halibut, and Greenland turbot. These fish are secondary consumers, as they feed on smaller organisms like krill and other zooplankton. Zooplankton, such as copepods and shrimp, are primary consumers, as they feed on algae and other plant material. Therefore, narwhals are tertiary consumers, as they occupy the third trophic level in the marine food chain.
