Using the data from the table above, which of the following statements best identifies and describes the organism or organisms with the smallest tolerance range to a change in pH in an aquatic environment? The frog and the perch have a critical pH of about 4, indicating that they can tolerate small changes in the acidity of their aquatic environment. The snail has a critical pH of 6, indicating that it can tolerate small changes in the acidity of its aquatic environment. The snail and the clam have a critical pH of 6, indicating that they can tolerate small changes in the acidity of their aquatic environment. The frog has a critical pH of 4, indicating that it can tolerate small changes in the acidity of its aquatic environment.
