B) less baby trout will live to adulthood
C) there won't be a change in baby trout populations

How does keeping lakes at natural, ideal pH levels affect the fish industry?

C) less fish are able to survive in the lakes and less money will be made from catching fish
D) more fish are able to survive in the lakes and more money will be made from catching fish

What is one disadvantage of testing aquatic creatures to see what their pH tolerances are?
