Question

why does the flow of acid rain in river make the survival of aquatic life in the river difficult

Answer 1

hey mate!

Acid rain also affects aquatic life and surface waters, by changing the pH level in bodies of water.  When there is a high amount of sulfuric acid, it interferes with a fish’s ability to take in nutrients, salt, and oxygen.  For freshwater fish, this acid affects their ability to maintain a balance between minerals and salts in their tissues, which the need to survive.  This acid also results in mucus forming in their gills, causing them to not get adequate amounts of oxygen.  This change in pH level impairs some of the fish’s ability to maintain their calcium levels, causes an imbalance of salt in their tissues, and impairs the reproduction ability of the fish.

hope this helps!

Answer 2

The ecological effects of acid rain are most clearly seen in aquaticenvironments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.
