Answer:
i) the death of fish in lakes
ii) precipitation with a ph as low as 3.0
Explanation:
Burning fossil fuels releases oxides of sulfur and nitrogen into the atmosphere. The release of this air pollutants can result in the death of fish in lakes, and in precipitation with a ph as low as 3.0.
Acid is formed in water bodies such as lakes when the air pollutants dissolve in water vapor. There is condensation of the acidic water vapor into the clouds, and it will later fall as precipitation (with a ph as low as 3) such as acid rain. The acid rain will eventually enter water bodies and make the water bodies to be more acidic. Acidic environment is harmful to aquatic organisms such as fishes and it can lead to their death.
