Question

According to MacArthur and Wilson's hypothesis of island biogeography, species immigration and extinction rates on a particular island correlate to __________.

A) the island's size and distance from the mainland
B) when the island formed
C) the number of other islands in the archipelago
D) how the island formed
E) the island's stage of ecological succession

Answer 1

The correct answer will be- Option-A

Step-by-step explanation:

The Theory of Island Biogeography was proposed by the MacArthur and Wilson's in 1967 which proposed that the number of species-immigration and extinction rates are determined by the size of the island and distance of the island from the mainland.

The suggestions made by them are:

1. The islands which remain farther from the mainland receive very few species as compared to the closest mainland.

2. Smaller island shows a high rate of species extinction as compared to the larger island.

Thus, option-A is the correct answer.
