In highly populated regions, large amounts of runoff, caused by development, can run into nearby streams. This runoff can be warmer than the existing water in the stream. This warm runoff will most likely
a
increase the amount of oxygen available to organisms in the water.
b
cause the stream to become cleaner by killing bacteria with the heated water.
c
decrease the amount of nitrogen for plants in the soil under the water.
d
kill some species of fish as they cannot handle the higher temperature of water.
