When can acid rain water be more harmful to aquatic organisms?
Answer and explanation
Correct answer: When the pH of water decreases greatly
The pH scale indicates the acidity or basicity of water: lower pH means greater acidity. Aquatic organisms, eggs, and food webs generally function within particular pH ranges. If acid rain lowers the pH greatly, physiological processes can be disturbed and sensitive organisms may die or reproduce poorly. Option A is correct. A pH of 7 is neutral, visual clarity does not determine pH, and every body of water has a temperature.
