Question

An oligotrophic lake is characterised by

• A. great changes in water level
• B. long food chains
• C. low nutrient contents and little life
• D. high nutrient levels and abundant flora and fauna

Answer 1

The correct option is C low nutrient contents and little life

An oligotrophic lake is a lake with low primary productivity, as a result of low nutrient content. These lakes have low algal production, and consequently, often have very clear waters, with high drinking-water quality.

So, the correct option is 'low nutrient contents and little life'.
