WEBAug 6, 2021 · Each layer on the pyramid represents a position in the food chain, called a trophic level. A pyramid food chain diagram reminds us how it takes many organisms in lower trophic levels to support a just few organisms in higher trophic levels. Food chains vary in length. Some may be short, with as few as two tropic levels.
