A. Deoxygenation
B. De-Nitrogenization
C. Eutrophication
D. All of these
🧠 Explanation:
Eutrophication occurs when dead plants on water surfaces deplete oxygen, harming aquatic ecosystems. Caused by nutrient runoff, it leads to algal blooms and fish deaths. For environmental science students, this process highlights water pollution, making it a key topic for studying aquatic ecosystems, environmental management, and pollution control. Eutrophication affects water quality, biodiversity, and human health, requiring sustainable solutions. Understanding it reveals the impact of human activities on natural systems. Studying eutrophication aids in developing strategies for water conservation, nutrient regulation, and ecosystem restoration, making it essential for addressing global environmental challenges and promoting sustainable water management practices.
