Question

Why would a biologist want to know the pH of a lake?
What would be the expected pH value for a normal, healthy lake?
What could be a possible outcome if the lake pH was too high or too low?
What could cause a large change in a lake’s pH?

Please help! I need to get this done no later than today!

Answer 1

Why would a biologist want to know the pH of a lake?
