Name the trophic levels in an ecosystem and explain how energy moves through the trophic levels. use the terms food chain and food web in the discussion.

Generally there is maximum four trophic levels in ecosystem- producers, primary consumers, secondary consumers and tertiary consumers.

Explanation:

ALL four trophic levels are arranged by their food chain. produces on the bottom trophic level with higher biomass and highest energy. Primary producers are dependent on producers for their food and form second trophic level with less biomass and 10% of energy than producers. Carnivorous are the secondary consumers depend on producers and primary consumers for their food. they consist of only 10% of energy than primary consumers. Omnivorous are on the top of the food web or the food chain with the least energy which is 10% of secondary consumers.
