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: -Organisms that depend on plants or autotrophs for food are called heterotrophs, and the mode of nutrition is known as heterotrophic nutrition. 2. Autotrophs are called producers as they make food required by all other organisms. Heterotrophs are called consumers as they consume food prepared by autotrophs.

Detailed explanation-3: -Omnivores are heterotrophs that consume both plants and animals. They include pigs, brown bears, gulls, crows, and humans. Omnivores actually fall on a continuum between herbivores and carnivores. Some omnivores eat more plants than animals, whereas other omnivores eat more animals than plants.

Detailed explanation-4: -Consumers include all animals and fungi and many protists and bacteria. They may consume autotrophs or other heterotrophs or organic molecules from other organisms.

Detailed explanation-5: -Which organisms are both autotrophs and heterotrophs? Cyanobacteria are organisms that are both autotrophs and heterotrophs. They exhibit photoautotrophic nutrition. Archaea is another example of organisms that are both autotrophs and heterotrophs.
