Question

5 how do plants that treat water reduce water pollution? choose two. they add nutrients to polluted water they purify the water before it is released into natural sources they increase the temperature of the water they spread pollutants across the water

Explanation:

Plants that treat water can purify it by absorbing pollutants, etc., reducing the amount of contaminants before release into natural water sources. Adding nutrients doesn't reduce pollution, increasing water - temperature isn't related to pollution reduction by plants, and spreading pollutants is harmful, not a reduction method.

Answer:

They purify the water before it is released into natural sources
