Morphology

oligotrophic = trophic (opaque) = oligo + troph + ic

Built from scientific combining forms ('oligo-' + 'trophic'); these are not productive or familiar to an average B1 learner, so the meaning is not reliably derivable.

Etymology

The word oligotrophic comes from Greek parts oligo- meaning 'few' and -trophic from trophē meaning 'food', the same idea behind nutrition. So an oligotrophic lake or soil has 'few nutrients' and supports very little plant or animal life.
