Question

To test acidity levels of water, scientists test pH. As acid rain falls, the pH level of the water in lakes and streams decreases. While certain animals can tolerate low pH levels, others are extremely sensitive to the effects of acid rain and cannot live under these conditions. Candice is working on a project to determine whether acid rain is causing a decrease in the number of bass and mayflies in a lake in her hometown. Candice takes a sample of the pH level of the lake, and she finds that the pH level is 5.4. What might Candice predict as a result of her findings

Answer 1

The lake's pH level of 5.4 is decreasing the amount of bass and mayflies.

hope this helps :)

Answer 2

The correct answer would be- the amount of bass and mayflies will decrease due to the acidic environment.

Step-by-step explanation:

Bass and mayflies are insects that are sensitive to high acidic water or soil. These organisms can not live under 5.5 pH and there will be a decrease in the number of this organism with a further decrease in pH value.

Candice found that the pH level of the lake is 5.4 which is below the sensitive level of bass and mayflies will result in decreases in the amount of these organisms.

Thus, the correct answer is - the amount of bass and mayflies will decrease due to the acidic environment.
