Aquatic ecosystems that are most readily damaged by acid are those that lack an important buffer that dissolves into the runoff after a precipitation event. What is this buffer?
A)calcium
B)carbonic acid
C)nitrate
D)bicarbonate
E)sulfate

Question

Quizplus · Accepted Answer

The buffer that dissolves into runoff after a precipitation event and helps prevent acidification of aquatic ecosystems is bicarbonate. It acts as a neutralizer, reacting with acidic compounds and preventing the pH levels from dropping too low. Therefore, aquatic ecosystems that lack bicarbonate as a buffer are more susceptible to acid damage.
