Question

An Oligotrophic Lake has
1. High levels of nutrients in water
2. High aquatic productivity
3. Algel Blooms
4. Low nutrients and low productivity

Answer 1

Correct Answer - Option 4 : Low nutrients and low productivity

The correct answer is Low nutrients and low productivity.

• An Oligotrophic Lake has low nutrients and low productivity.
• These lakes have low algal production, and consequently, often have very clear waters, with high drinking-water quality.

 

• 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.
• Oligotrophic lakes are most common in cold, sparsely developed regions that are underlain by crystalline igneous, granitic bedrock.
• Due to their low algal production, these lakes consequently have very clear waters, with high drinking-water quality.
• Lakes that have to intermix their layers are classified into the category of holomictic, whereas lakes that do not have interlayer mixing are permanently stratified and thus are termed meromictic.
