उत्तर
An oligotrophic lake is characterised by low nutrient contents and little life.
Explanation:
These lakes have low organic matter productivity due to nutrient scarcity. As a result, they support less flora and fauna than nutrient-rich water bodies. The limited nutrients limit biological activity and aquatic life in such lakes, making them less biologically productive overall.
