Which term describes an organism that makes its own food?

• A. Consumer
• B. Producer
• C. Decomposer
• D. Ecosystem

Answer: (B)

Organisms that make their own food are called producers (autotrophs). They capture energy—primarily from sunlight—and convert inorganic materials like carbon dioxide and water into organic compounds that fuel their growth. This ability places them at the base of the food chain, supporting all other organisms that rely on them for energy. A producer example is plants, along with algae and some bacteria that perform photosynthesis. In contrast, a consumer must eat others for energy, a decomposer breaks down dead matter to recycle nutrients, and an ecosystem refers to the whole interacting system, not a single organism. So the term that best fits an organism that makes its own food is producer.
