LIFE SCIENCE

Detailed explanation-1: -A heterotrophic organism, sometimes simply referred to as a heterotroph, is an organism that must obtain its nutrition by consuming other organisms or the organic matter from a once-living organism. Humans, cats, and rabbits are all examples of heterotrophic organisms.

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.
