Root Explanation

Heterotrophic → It is formed from "hetero-" (from Greek "heteros", meaning different) and "trophic" (from Greek "trophē", meaning nourishment or feeding). The word describes organisms that obtain their nourishment from different sources, as opposed to producing it themselves.

Memory Tip

Think of 'different' ('hetero-') ways of 'feeding' ('trophic') — that's why heterotrophic refers to organisms that get their nourishment from various external sources.
