An organism that makes its own food from inorganic sources is called a(n) ______.

Explanation:
Autotrophs are organisms that convert inorganic materials into organic food. They capture energy from light (photosynthesis) or from chemical reactions with inorganic substances (chemosynthesis) to turn carbon dioxide and water into organic molecules like glucose. This ability to make their own organic matter is what bases the food chain, with plants, algae, and many bacteria as examples. Other options describe organisms that obtain energy by eating other organisms (heterotrophs and consumers) or by breaking down dead material (decomposers), which does not involve making organic molecules from inorganic inputs.
