What Are Trophic Levels?

The video explains trophic levels in a food chain, starting with primary producers like plants, followed by primary consumers (herbivores), secondary consumers (carnivores that eat herbivores), tertiary consumers (carnivores that eat other carnivores), and apex predators at the top. Decomposers, which break down dead matter, also have a trophic level. The video provides an example with grass, rabbits, foxes, eagles, and fungi to illustrate these levels. It concludes by summarizing the roles of each trophic level in an ecosystem.
