Answer
B
Work Step by Step
The greatest effects of acid deposition have been on the aquatic ecosystem. Lower ph values of water bodies has caused a decrease in species diversity of aquatic organisms. Many species are able to survive and reproduce only within a narrow range of environmental conditions. For example, many amphibians will survive when the pH value of a lake is 6.5, but when the lake acidifies to pH 6.0 or 5.5, the same organism will begin to have developmental or reproductive problems.
