Question

The lakes with a reduced profundal zone and a highly productive littoral and sublittoral zones are termed as
Options
A Oligotrophic
B Dystrophic
C Eutrophic
Correct Answer
D Mesotrophic
Correct Answer

Option C is the correct answer.

Detailed Explanation

Eutrophic lakes are characterized by high nutrient content (especially nitrogen and phosphorus), high primary productivity, and often a reduced profundal zone due to shallowness or sediment filling. They typically have abundant littoral (shore) and sublittoral (near-shore) vegetation and may experience algal blooms and oxygen depletion. Oligotrophic lakes are nutrient-poor and deep; dystrophic lakes are acidic and stained by humic acids; mesotrophic lakes are intermediate.

Hint

Which type of lake is nutrient-rich, highly productive, and often has a well-developed littoral zone?
