The equilibrium theory of island biogeography predicts that the number of species found on an island: a. increases steadily until it equals the number in the mainland species pool. b. is greater on large islands than on small ones. c. is smaller on islands near the mainland than on distant islands. d. can never reach an equilibrium number. e. is greater for islands near the equator than for islands near the poles.

The theory of island biogeography $a.$ predicts that the equilibrium number of species on an island is a balance between the rate of immigration of new species and the rate of extinction of resident species. $b .$ predicts that the rate of immigration of new species will decline with island distance from the mainland species pool. $c.$ predicts that the rate of extinction of resident species will decrease as island size increases. $d$. applies to isolated habitat patches as well as to oceanic islands $e .$ all of the above
