LIFE SCIENCE

Detailed explanation-1: -Horses are herbivorous animals. They eat grass, plants but they do not produce their own food. Animals that don’t produce their own food and are dependent on plants or other animals are known as heterotrophs. Hence, horses are heterotrophs.

Detailed explanation-2: -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-3: -In the food chain, heterotrophs are primary, secondary and tertiary consumers, but not producers. Living organisms that are heterotrophic include all animals and fungi, some bacteria and protists, and many parasitic plants.
