Energy flow between trophic levels is another ecological concept. Trophic levels are the feeding position in a food chain. This food chain involves primary producers, herbivores, primary carnivores, and more. Plants are producers and in the first trophic level, herbivores form the second level, and carnivores from third and fourth trophic levels.
