Which term best describes an organism that preys on other heterotrophs?

• A. Autotroph
• B. Detritovore
• C. Carnivore
• D. Decomposer

Answer: (C)

Feeding on other heterotrophs means acting as a consumer that targets animal life. An organism that preys on other heterotrophs fits the term carnivore, since carnivores rely on animal tissue for energy and nutrients. An autotroph makes its own food through photosynthesis or chemosynthesis, not by preying on others. A detritivore eats detritus—dead organic matter—rather than living heterotrophs, and a decomposer breaks down dead material to recycle nutrients. So the term that best describes preying on other heterotrophs is carnivore.
