Construct an explanation that answers the following question, "If the pH off the pond dropped to 5.5, how would organisms living in the pond be affected?"

Some organisms are affected.

Explanation:

If the pH of the pond dropped to 5.5, some of the organisms living in the pond affected because most of the organisms present in the graph lives in highly acidic and slightly acidic water so when the pH is dropped to 5.5, only frog and perch are greatly affected and decrease in its population occurs while the other organisms are not greatly affected with the change of this pH.

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?
