A trophic level refers to a level or a position in a food chain or ecological pyramid. It is occupied by a group of organisms that have a similar feeding mode. At the base of an ecological pyramid is trophic level 1. A food chain would start as well at trophic level 1. The trophic level 1 is occupied by the primary producers (e.g. plants).
In the simplest scheme, the first trophic level (level 1) is plants, then herbivores (level 2), and then carnivores (level 3). The trophic level is equal to one more than the chain length, which is the number of links connecting to the base.The base of the food chain (primary producers or detritivores) is set at zero.n the simplest scheme, the first trophic level (level 1) is plants, then herbivores (level 2), and then carnivores (level 3).
