Question

Quizplus · Accepted Answer

Heterotrophs obtain carbon from organic compounds in their food and energy from the breakdown of these compounds. Chemotrophs obtain energy from chemical reactions, while autotrophs produce their own organic compounds using an external source of energy such as sunlight (phototrophs) or chemical reactions (chemotrophs). Therefore, the description matches with 2 and 4, which are heterotrophs and obtain energy from chemical reactions.
