These blooms can reduce oxygen levels in the water, harming aquatic life. The best answer to the question is D: Excess nutrients promote the growth of algae. ;
The primary cause of eutrophication in lakes is the introduction of excess nutrients, particularly nitrogen and phosphorus, leading to algal blooms. This can deplete oxygen levels in the water, negatively impacting aquatic life. Therefore, the correct answer is D: Excess nutrients promote the growth of algae.
