Question

Quizplus · Accepted Answer

Plant nutrients, particularly nitrogen and phosphorus, can cause excessive growth of algae through a process called eutrophication. These nutrients come from various sources such as industrial runoff, agricultural activities, and household waste. As the algae population increases, it can cause harm to aquatic ecosystems by depleting oxygen and blocking sunlight, which can negatively impact other aquatic life.
