A) using advanced waste treatment systems.
B) adding aquatic weeds to the water body to absorb excess oxygen.
C) harvesting excess weeds.
D) pumping air through reservoirs to avoid oxygen depletion.
E) limiting or banning phosphates in detergents.

Question

Quizplus · Accepted Answer

Adding aquatic weeds to the water body to absorb excess oxygen is not a method of controlling cultural eutrophication because cultural eutrophication is caused by an excess of nutrients, especially phosphates and nitrates, which lead to the growth of algae that consume oxygen from the water. Aquatic weeds absorb oxygen during the day and release it at night, so they do not address the root cause of cultural eutrophication. The other choices are methods of controlling cultural eutrophication because they either remove excess nutrients (harvesting weeds), reduce nutrient inputs (limiting or banning phosphates in detergents), or provide oxygen to the water (using advanced waste treatment systems and pumping air through reservoirs).
