The presence of acid rain in an ecosystem has multiple repercussions, impacting both the water supply and the flora and fauna within that particular area. In aquatic ecosystems, acid rain poses a threat to various aquatic organisms such as fish, insects, and other wildlife. The decrease in pH levels can lead to the death of numerous adult fish, while a pH drop below the normal range inhibits the hatching process of fish eggs.
