Root Explanation

Ectotrophic → It is formed from "ecto-" (from Greek "ektos", meaning outside) and "trophic" (from Greek "trophikos", meaning relating to nourishment or feeding). The word describes organisms that obtain nutrients from outside sources, particularly in their environment.

Memory Tip

Think of 'outside' ('ecto-') and 'nourishment' ('trophic') to remember that ectotrophic refers to organisms that feed from external sources.
