Study the picture given below and answer the following question: Identify the type of pollution.

The contamination of water bodies usually caused due to human activities is called water pollution. The type of pollution shown in the given image is water pollution. The causes of water pollution are domestic waste, industrial effluents, insecticides, pesticides and detergents, fertilizers. As these pollutants get mixed with the water the aquatic animals will not get sufficient oxygen gas for respiration which ultimately leads to the death of aquatic animals.

Study the picture given below and answer the following question: State one measure to control this pollution.

The contamination of water bodies usually caused due to human activities is called water pollution. The causes of water pollution are domestic waste, industrial effluents, urbanization, fertilizers. The steps to prevent water pollution are as follows: Trees or plants should be planted along the banks of rivers. Pollutants from industries should not be discharged into the water bodies.

Study the picture given below and answer the following question: Name one pollutant that causes the above pollution.

The contamination of water bodies usually caused due to human activities is called water pollution. The causes of water pollution are domestic waste, industrial effluents, insecticides, pesticides and detergents, fertilizers.
