Question

Aquatic animals have different levels of tolerance to pH scale changes in water. For example a wood frog will die if the pH of water falls below 4while a clam will die if the pH of water falls below 6 what can you conclude about the acidity of water in a river if both wood frogs and clams survive?

Answer 1

the pH level needs to be higher in order for the frog and clam to survive so the acidity will be low. Hope this helps.
