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?\na there are more species that have the ability to travel 5 kilometers than can travel 15 kilometers.\nb islands that are closer to continents always have a wider range of habitats than more distant islands do.\nc there are smaller populations of each species on islands that are at greater distances from continents.\nd islands that are closer to continents always have more ecological niches than more distant islands do.

Answer

Brief Explanations:

According to the theory of island biogeography, the distance of an island from a continent affects species immigration. Islands closer to continents (like 5 km) are more accessible to a greater number of species that can travel the shorter distance compared to the longer 15 - km distance. Options B and D are incorrect because the range of habitats and number of ecological niches are not directly related to distance from the continent in this context. Option C is about population size, not the number of species.

Answer:

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