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: -Decomposers are heterotrophs that break down and feed on the remains of dead organisms and other organic wastes such as feces. In the process, they release simple inorganic molecules back to the environment.
