Can you please put the graph in the question so I can see it?

Acids have a pH level power than 7. Water is usually close to 7 pH, but it is usually diluted because of various factors. I'm assuming you mean the pH of the sample was 5.4? This would make more sense. The acid rain would lower the average pH because the rain has a pH less than 7. The rain's pH will also be less than 5.4 because it would need to average with the waters previous pH to get this number.

This bar chart represents at the pH levels at which certain animals cannot live. The lower pH levels begin to negatively affect some animals. Bass and mayflies cannot live in a condition with a pH level below 5.5. Therefore, a pH level of 5.4 is extremely dangerous for both bass and mayflies. Candice can draw the conclusion, based on the chart, that The lake's pH level of 5.4 will cause a decrease in the amount of bass and mayflies. in her hometown.
