Question

Quizplus · Accepted Answer

The two groups, autotrophs and heterotrophs, differ in their mode of nutrition. Autotrophs are organisms that make their own food using energy from the sun or another non-living source, while heterotrophs are organisms that obtain their food by consuming other organisms. The other options (A, B, D) are not descriptive enough to accurately distinguish between the two groups.
