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: -Heterotrophs are the organisms that do not contain chlorophyll pigment like autotrophic animals. Thus, they cannot carry out the process of photosynthesis which is essential for the preparation of food.

Detailed explanation-3: -Heterotrophs cannot synthesize their own food and rely on other organisms(both plants and animals) for nutrition.

Detailed explanation-4: -Organisms that depend on other sources for food are called heterotrophs.
