Why a heron a tertiary concumer?

Answer 1

A heron is considered a tertiary consumer because it primarily feeds on smaller animals, such as fish, amphibians, and invertebrates, which are themselves secondary consumers or primary consumers. In the food chain, tertiary consumers occupy the third trophic level, where they are typically predators that help regulate the populations of these lower-tier organisms. By preying on these species, herons play a crucial role in maintaining ecological balance within their habitat.
