What is the trophic level?

The trophic level of a living being is the place it settles in a food web. The trophic level of a living thing is the number of phases it is from the start of the chain.

A food web begins at trophic level 1 with basal producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and generally end with height wolves at level 4 or 5.
