Acid rain throughout the northeast United States has lowered the pH of many ponds and lakes. The lowered pH will eventually result in the death of many aquatic animals. The table shows the pH tolerance levels for water that supports a variety of nine animal species living in a specific habitat. Which animal has the largest zone of tolerance for pH?

Perch - Acid tolerance of up to pH 4.5

Frogs - Acid tolerance of up to pH 4.0

Salamander - Acid tolerance of up to pH 5.0

Clams - Acid tolerance of up to pH 6.0

Crayfish - Acid tolerance of up to pH 5.5

Snails - Acid tolerance of up to pH 6.0

Mayfly - Acid tolerance of up to pH 5.5

snail

Explanation:

Snails generally do not survive in acidic water. This is one of the main reasons why they cannot be found in lakes with low calcium. They tend to survive in a region with low pH. In the question above, there is the presence of low pH due to acid rain in the United States. This is suitable for the survival of snails. Thus, they have the largest tolerance zone.
