Which of the following correctly describes heterotrophs?

• A. They can synthesize their own food
• B. They are primary producers
• C. They cannot produce their own food
• D. They primarily consume autotrophs

Answer: (C)

Heterotrophs are organisms that cannot produce their own food and instead rely on consuming other organisms for their energy and nutrients. This characteristic distinguishes them from autotrophs, which can synthesize their own food through processes such as photosynthesis or chemosynthesis. Heterotrophs include a wide variety of organisms, such as animals and fungi, that must obtain organic compounds from external sources, such as plants, other animals, or decomposing organic matter. Given this understanding, the option stating that they cannot produce their own food correctly highlights the defining feature of heterotrophs. While some heterotrophs may consume autotrophs, this is not a universal trait as heterotrophs can also derive nutrients from other heterotrophs or decomposing material. In contrast, the other options either suggest abilities or classifications tied to autotrophs or primary producers, which do not apply to heterotrophs.
