Which of the following is a characteristic of autotrophs?

Autotrophs are organisms that have the unique ability to produce their own food through processes such as photosynthesis or chemosynthesis. This characteristic allows them to convert inorganic materials into organic substances, which can serve as energy sources for themselves and, indirectly, for other organisms in the ecosystem. For instance, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen through photosynthesis. This self-sufficient method of obtaining energy distinguishes autotrophs from heterotrophs, which must consume other organisms to obtain their food. The ability to synthesize their own food is fundamental to their role in the food chain and ecosystem stability.
