Tertiary consumers depend on the sun for food. true or false

It is false that tertiary consumers depend on the sun for food.
Tertiary consumers are at the top of the food chain, meaning that they are usually carnivores that eat other carnivores. Thus, they depend on other organisms for food, and not on the Sun. Primary consumers are various plants that depend on the Sun, whereas secondary consumers are small creatures.
