Eutrophication is nutrient enrichment of water bodies, primarily lentic. It leads to algal blooms, accumulation of organic matter, and ultimately oxygen depletion, which is detrimental to aquatic life. While initial increased productivity might support some organisms, the overall effect is negative.
Which of the following statements about Eutrophication is/are correct? (a) The eutrophication occurs in lotic water body primarily in hilly region. (b) The eutrophication occurs in lentic water and there is gradual accumulation of organisms and their products. (c) The eutrophication promotes fish growth as algal blooms serve as source of food to fishes. (d) The eutrophicated water is oxygen rich and safe for human consumption without treatment.
