According to the theory of island biogeography, those islands that are further isolated from the mainland and other islands would be expected to have
a. more species
b. fewer species
c. more genetic variation
d. more immigration to the islan

The correct answer is - b. fewer species.

The remote isolated islands were the ways are closed for any migration of species from other islands or from the closest mainland are having fewer species. This is due to the fact that migration of other species to the island is not possible or can be performed by only few species (usually birds), so the flora and fauna on the island over time is specializing and competing between itself and because of the limited resources some of the species die out, so the island only has highly specialized small amount of species.
