Conversation

Have you ever heard of an oligotrophic lake?

Yeah, I read that they have a lot of oxygen but not many nutrients.

Exactly! It makes them pretty unique for certain types of fish.

That’s interesting! I’d love to see one in person.

Root Explanation

Oligotrophic → It is formed from "oligo-" (from Greek "oligos", meaning few or little) and "trophic" (from Greek "trophikos", meaning relating to nourishment or feeding). The word describes environments that have low nutrient levels, hence supporting fewer organisms.

Memory Tip

Think of 'few' ('oligo-') nutrients leading to 'little' growth or life in an environment, which is what oligotrophic means.
