Oligotrophic lakes are significant to ecosystem health due to their low nutrient levels, which result in high water clarity and support unique biodiversity. These lakes provide critical habitats for various species, including sensitive aquatic organisms, and play a role in carbon sequestration. The limited nutrients help prevent excessive algal blooms, which can degrade water quality and disrupt aquatic ecosystems. Consequently, maintaining the integrity of oligotrophic lakes is essential for sustaining local biodiversity and promoting a balanced ecosystem.
