According to MacArthur and Wilson's theory of island biogeography, which of the following is correct?
a. The number of species decreases with island isolation.
b. Smaller islands have wider variety of habitat and niches than larger islands.
c. The number of species decreases with island area.
d. The number of species increases with island isolation.
e. No relationship is recognized between species number and island isolation.
According to MacArthur and Wilson’s Island Biogeography theory, the 'number of species decreases with island isolation'.
It also states that the more the area of the island, the more increase in the number of species.
EXPLANATION:
The Island biogeography was a theory coined by 'E.O. Wilson and Robert MacArthur' in 1967.
This theory explained how the area and distance of an island population combined to adjust the balance between 'extinction' and 'immigration' of the population of the 'species' living in the island.
