An organism that produces its own food supply from inorganic compounds is called a(n) ____.

Explanation:
Organisms that can make their own food from inorganic materials are autotrophs. They build organic molecules, like glucose, using energy from light (photosynthesis) or from chemical reactions (chemosynthesis), starting from inorganic substances such as carbon dioxide and water. These producers form the base of ecosystems by supplying energy and organic matter for other organisms. Heterotrophs, in contrast, must obtain energy by consuming other organisms. A consumer is a heterotroph that eats living or once-living organisms, and a decomposer feeds on and breaks down dead material.
