Choose the best definition for the term autotrophic?

Autotrophic refers to organisms that can produce their own food using inorganic substances, typically through processes like photosynthesis or chemosynthesis. These organisms, such as plants, algae, and some bacteria, convert sunlight or chemical energy into organic compounds. Autotrophs are essential to ecosystems as they form the base of the food chain, supplying energy to heterotrophic organisms that cannot synthesize their own food.
