"Some types of plants and animals are able to tolerate acidic waters.
Others, however, are acid-sensitive and will be lost as the pH declines.
Generally, the young of most species are more sensitive to environmental
conditions than adults. At pH 5, most fish eggs cannot hatch. At lower pH
levels, some adult fish die. Some acid lakes have no fish. The chart below
shows that not all fish, shellfish, or the insects that they eat can
tolerate the same amount of acid; for example, frogs can tolerate water
that is more acidic (has lower pH) than trout"
