Safeopedia explains Trophic Level

There are several trophic levels in a food chain, which include primary producers, primary consumers, secondary consumers and tertiary consumers. The primary trophic level contains primary producers including plants and microorganisms or any organism that makes it's own food from sunlight, or other primary energy sources and does not eat other organisms. The second trophic level includes the organisms that consume these, such as plant eating animals or primary consumers. The other levels include the organisms that consume the primary consumers (secondary consumers) and the organisms that consume the secondary consumers (tertiary consumers).
