Answer:
Acid rain also known as acid deposition can come in any form of precipitation. It is basically precipitation with acidic components, such as sulfuric or nitric acid. It can come from sulfur or coal fumes.
It can be destructive to the ecosystem. Most animals aren't immune to the low pH levels and get harmed or die from it. The animals/plants that are immune suffer greatly by loss of food. You will most likely see dead plants and trees from the areas that have acid rain.
