Bass - Acid tolerance of up to pH 5.5
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
Answer:
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.
