A particular stream is home to several species of fish that are sensitive to fluctuations in the pH of the water. Every time it rains, fertilizer runoff from nearby farms enters the stream, which changes the pH of the water. Which activity could increase the stream’s carrying capacity for this type of fish?

A moving the fish to another ecosystem farther downstream
B adding new fish to the stream after every major rainstorm
C closely monitoring the pH of the stream
D stopping the farms from using fertilizers
