Answer 2

Eutrophication causes a growth of the layer of algae on the water surface which decreases the amount of oxygen in the water.

Explanation:

• The fertilisers and pesticides in areas cause eutrophication. When either they flow into the earth and combine with groundwater, or they are destroyed with drain and rain into the rivers, the accumulation of these pollutants in water bodies increases. This is known or called eutrophication.
• Eutrophication causes a growth of the layer of algae on the water surface which decreases the amount of oxygen in the water.
• If other aquatic plants and animals die from lack of oxygen, their dead remain serve as nutrition for bacteria which further decreases the oxygen levels in water sources.
