Quizplus · Accepted Answer

Heterotrophs obtain carbon by ingesting other organisms and energy from the organic molecules in those organisms. Chemotrophs obtain energy by oxidizing chemical compounds and may obtain carbon from either organic or inorganic sources. Autotrophs obtain carbon from inorganic sources like carbon dioxide and energy from either sunlight (phototrophs) or chemical compounds (chemotrophs). Since this description specifically mentions ingestion, it rules out phototrophs and leaves us with heterotrophs and chemotrophs. Therefore, the best choice(s) are D (heterotroph and chemotroph).
