Quizplus · Accepted Answer

Oligotrophic lakes are characterized by low nutrient content, leading to low productivity. Such lakes typically have clear water with little aquatic plant life or planktonic growth (C), allowing visibility to the bottom (D). The shoreline of an oligotrophic lake is often rocky or sandy with minimal vegetative decay (A), contributing to the low nutrient levels.
