Quizplus · Accepted Answer

Organisms that use carbon dioxide gas as their primary source of carbon are autotrophs. They are able to produce their own organic compounds using carbon dioxide and energy from sunlight or chemical reactions. Heterotrophs, on the other hand, obtain their carbon from organic compounds produced by other organisms. Fungi and free-living organisms can be either autotrophs or heterotrophs, so they are not the best choices. Commensals, meanwhile, refer to organisms that live in close association with another organism without causing harm or benefit.
