Acid rain can have a severe negative impact on forests. Calcium and magnesium, two elements that trees need for optimal health, can be destroyed by acid rain reaching the earth. Acid rain also releases aluminum into the soil, which reduces trees' capacity to absorb water.
Thus, Option B is correct.
Acid rain can injure fish and other wildlife, therefore it has an adverse influence on the ecology of aquatic areas like streams, lakes, and marshes. Acidic rainwater can dissolve aluminum from soil clay particles as it percolates through the soil and then enters streams and lakes. Aluminum is discharged in more significant quantities the more acid is added to the ecosystem.
Some plants and animals can tolerate acidic waters with small levels of aluminum. However, some are acid-sensitive and will disappear when the pH drops. Most species' young are typically more susceptible to environmental factors than adults are.
