Detailed explanation-1: -The acids in the rain can leach nutrients from the soil, making it difficult for plants and trees to grow. Trees are also affected by acid rain, as the acidity damages, and their bark and roots inhibit their ability to absorb nutrients from the soil. Over time, this can lead to deformities, weak growth, and even death.

Detailed explanation-2: -Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.

Detailed explanation-3: -The effects of air pollution on plants are: (i) Sulphur dioxide bleaches the surface of the leaves, causes loss of chlorophyll and results in yellowing of the leaves, especially in green leafy vegetable. (ii) Nitrogen dioxide results in the premature falling of leaves and suppressed growth of plants.

Detailed explanation-4: -Young rootless or small root plants are more likely to be affected severely. Excess acid in soils can dissolve the soil substrate, leading to erosion. Acid rain removes minerals and nutrients from the soil, which are essential for plant growth. Drops of acid rains suck out the nutrients from the plant leaves.

Detailed explanation-5: -Ans: Acid rain and fog both harm forests, particularly those at higher elevations. Acid deposits deplete the soil of essential nutrients such as calcium and cause aluminium to be released into the soil, making it difficult for trees to absorb water. Acids also harm the leaves and needles of trees.
