Figure 52.11
-Which of the following statements regarding the figure above is true?
A) Extinction rates are highest on large islands close to the mainland. 
B) Species diversity should be highest on larger islands away from mainland. 
C) Immigration rates are higher on smaller islands. 
D) Species richness should be higher on larger islands close to mainland.

Quizplus · Accepted Answer

The figure shows that species richness increases with island size and proximity to the mainland. Therefore, species richness should be higher on larger islands close to the mainland (D). Choice A is incorrect because the graph does not provide data on extinction rates. Choice B is incorrect because the graph only shows species richness, not overall diversity (which would also include genetic and ecosystem diversity). Choice C is also incorrect because immigration rates are not shown in the graph.
