Answer» 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.
