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: -Animals cannot make food on their own. They depend on plants for their food either directly or indirectly. And therefore, nutrition in animals is said to be heterotrophic.

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: -Heterotrophic nutrition is a mode of nutrition in which organisms depend upon other organisms for food to survive. They can’t make their own food like Green plants. Heterotrophic organisms have to take in all the organic substances they need to survive.

Detailed explanation-5: -The heterotrophs are organisms that cannot make their food. They consume the food prepared by autotrophs or the autotrophs themselves. Hence, they depend on autotrophs for their nutritional requirements.
