Answer 2

Effect of air pollution on fishes:

• The burning of fossil fuel produces carbon dioxide.
• When the carbon dioxide mixes with the atmosphere, it produces carbon monoxide, nitrous oxide and other harmful gases.
• When these gases mix with the moisture present in the clouds, it forms acid.
• After attaining saturation, the acids fall as rain which is Acid Rain.
• When acids mix with lakes or ocean or other water resources, it makes unsuitable for the fishes to live.

Effect of water pollution on fishes:

• Now-a-days, to increase the yield and productivity, the farmers use more pesticides and insecticides which are chemicals.
• Due to over usage, these chemical has harmful effect on the soil and makes the soil more acidic.
• When the water from this acidic soil is let into river, it makes unsuitable for the fishes to live in it.
