APFIVE Biodiversity Index Calculation
Island biogeography theory often relates species richness to the size of the island and its distance from a source mainland. Suppose the biodiversity index is defined as $$B = \frac{Area}{Distance}$$. Based on the table above, which island has the highest biodiversity index and what is its value?
| Island | Distance (km) | Area (km^2) |
|---|---|---|
| X | 15 | 50 |
| Y | 30 | 120 |
| Z | 10 | 80 |
A
Island Y with a biodiversity index of $$4$$.
B
Island Z with a biodiversity index of $$6$$.
C
Island Z with a biodiversity index of $$8$$.
D
Island X with a biodiversity index of approximately $$3.33$$.
