Detailed explanation-1: -Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.

Detailed explanation-2: -A consumer is a heterotroph and a producer is an autotroph. Like sea angels, they take in organic moles by consuming other organisms, so they are commonly called consumers.

Detailed explanation-3: -Consumers are also referred to as heterotrophs in contrast to autotrophs, which are the producers of the food chain. Consumers therefore include animals and heterotrophic bacteria and fungi.
