Species richness increases:

Select one:

a. as we increase in altitude in equatorial mountains.

b. as community size decreases.

c. on islands as distance from the mainland increases.

d. as we travel southward from the North Pole.

e. as depth increases in aquatic communities.

Answer:

The correct answer is D)

Species richness increases as we travel southward from the North Pole.

Explanation:

Studies have shown that plant diversity for instance decrease in richness (and total plant cover) with elevation is due to the environmental severity which

increases with elevation because of coldness, short growing seasons, excessive radiation, and other factors.
