Which of the following best describes the transfer of phosphates and the impact on the environment and human health? Question 24 options: Phosphates decrease the growth of algae in surface water bodies, and an overpopulation of fish in surface water bodies occurs. Nitrates increase the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish. Leaky septic tanks transfer phosphates into the groundwater and are converted into nitrites in the human body, which are poisonous and could be fatal for infants. Detergents containing phosphates are carried from land to water by rain, contaminating drinking water and causing digestive problems in humans.

Nitrates increase the growth of algae in surface water bodies, killing fish.

Explanation:

Nitrates are used by algae as a food source and their excessive supply can result into uncontrolled growth of algal biomass. The phenonmenon of excessive growth of algae in a lake environment is known as eutrophication. When the growth of algae keeps increasing, it results into low sunlight penetration in the water body especially in deeper zones. Therefore, organsims inside water will consume all oxygen and the lack of oxygen will result into their death including fish population. Keep in mind that nitrates are not directly toxic to the fish or other animals. Instead, some studies have argued that nitrates are beneficial up to a certain limit
