Question

A researcher is comparing the species diversity of two islands. Both islands are roughly equal in size. However, one island is much closer to the mainland. She determines that the S value for the island closer to the mainland is _____ the S value for the island located farther from the mainland. In addition, she finds that the closer island's extinction rate is _____ the extinction rate on the farther island.
A. lower than; higher than
B. higher than; lower than
C. lower than; the same as
D. the same as: lower than
E. higher than; the same as
F. the same as; higher than

Answer 1

Answer:

higher than; the same as.

Explanation:

The Mac Arthur and Wilson theory of island bio geography states that island species is determined by the size and distance of island from the mainland. The island of large size and less distance accumulate more species.

The researcher compare the species of two island. According to the Wilson, she can determines that the S value is higher for the island located closer to mainland than from the island located far away. The extinction rate of both the islands are same.

Thus, the correct answer is option (e).
