What term describes an organism that captures energy from sunlight or chemicals to produce food from inorganic compounds?

Explanation:
The main idea is how an organism makes its own food by using energy to drive carbon fixation. Organisms that capture energy from light or from chemical reactions and use that energy to convert inorganic carbon (like CO2) into organic molecules are autotrophs. They are the producers of organic matter for their ecosystems, forming the base of the food web. The term autotroph specifically names this energy source and carbon source combination, making it the best fit for the description. Producers is a broader ecological role that can include autotrophs, but autotroph precisely matches the described mechanism.
