A
An organism that can make it’s own food.
B
An organism that breaks down decaying material.
C
An organism that has to eat other organisms to obtain energy.
D
An organism that only eats plants.
Explanation: 

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: -“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-3: -heterotroph, in ecology, an organism that consumes other organisms in a food chain. In contrast to autotrophs, heterotrophs are unable to produce organic substances from inorganic ones. They must rely on an organic source of carbon that has originated as part of another living organism.

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: -/ˌhet̬.ɚ.əˈtroʊ.fɪk/ (of a living thing) getting its food from other plants or animals, or relating to such living things: Carbon dioxide is utilized by heterotrophic organisms. There are high levels of heterotrophic bacteria in the aquarium. See.
