Which of the following is a characteristic of oligotrophic lakes?
A
Murky water.
B
Dense vegetation.
C
Summer turnover.
D
Relatively low biomass & primary productivity.
Verified step by step guidance1
Understand the term 'oligotrophic': Oligotrophic lakes are bodies of water that have low nutrient concentrations, which leads to low primary productivity.
Identify the characteristics of oligotrophic lakes: These lakes typically have clear water, low algal production, and are often found in mountainous regions or areas with little human impact.
Contrast with eutrophic lakes: Eutrophic lakes have high nutrient levels, leading to high primary productivity and often murky water due to dense algal blooms.
Consider the options given: Murky water and dense vegetation are characteristics of eutrophic lakes, not oligotrophic lakes.
Recognize the correct characteristic: Oligotrophic lakes are known for having relatively low biomass and primary productivity, which aligns with the definition and characteristics of oligotrophic lakes.
