Read the passage and answer the following questions:
Acid rain is formed after the burning of fossil fuels releases compounds containing nitrogen and sulfur into the atmosphere. Sunlight and rain bring about chemical reactions that convert these compounds into nitric acid and sulfur dioxide, which combine with water droplets to form acid rain. Acid rain typically has a pH of approximately 5.5. "The higher acidity of soil and water affects many living organisms adversely. As the pH of lake water falls, fish become ill and die. Table 1 shows the effects of pH on the size of adult fish.
pH of lake | Average length of fish (cm) | Average mass of fish (g) |
---|---|---|
7.5 | 30 cm | 454 g |
7.0 | 28 cm | 450 g |
6.5 | 29 cm | 453 g |
6.0 | 25 cm | 401 g |
5.5 | 20 cm | 288 g |
5.0 | 17 cm | 127 g |
4.5 | All fish died | All fish died |
Mycorrhizal fungi, which form a mutualistic association with many plant roots, are particularly sensitive to the effects of acid rain. These fungi facilitate the
absorption of water and nutrients by the plants; in turn, the plants provide sugars and amino acids without which the fungi could not survive.
Fungi are classified as
Acid rain is produced when rain mixes with chemicals such as sulfur dioxide in the air. This may result in

What might be the best strategy to prevent the death of the fishes?
Acid rain will not affect
Pollutant which causes acid rain is
The acid rain destroys vegetation because it contains

If the pH of the soil was 7.0, then
Acid rain occurs above the area where
