Detailed explanation-1: -A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.

Detailed explanation-2: -Answer and Explanation: Organisms that obtain their energy by feeding on other organisms are called heterotrophs. Autotrophs are living organisms that are able to make their own food through photosynthesis, and these are plants and algae. Organisms that must consume or absorb their nutrients are called heterotrophs.

Detailed explanation-3: -“Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.” All animals and non-photosynthetic plants are classified as heterotrophs since they are unable to prepare food.

Detailed explanation-4: -Heterotrophs are organisms that obtain energy from other living things. Like sea angels, they take in organic molecules by consuming other organisms, so they are commonly called consumers. Heterotrophs include all animals and fungi as well as many protists and bacteria.

Detailed explanation-5: -Heterotrophs cannot make their own food, so they must eat or absorb it. For this reason, heterotrophs are also known as consumers. Consumers include all animals and fungi and many protists and bacteria. They may consume autotrophs or other heterotrophs or organic molecules from other organisms.
