Based on the theory of island biogeography, which of the following is the most likely reason that an island in the ocean that is 5 kilometers from a continent would have a higher number of species than one that is 15 kilometers from a continent?

• There are more species that have the ability to travel 5 kilometers than can travel 15 kilometers.

• Islands that are closer to continents always have a wider range of habitats than more distant islands do.

• There are smaller populations of each species on islands that are at greater distances from continents.

• Islands that are closer to continents always have more ecological niches than more distant islands do.

Based on the theory of island biogeography, which of the following would most likely experience the greatest decline of specialist species if an invasive species emigrated from the mainland?

• A large island in close proximity to the mainland
