Question

an island that is closer to a continent has a higher number of species than one that is further from the same continent. which of the following supports the theory of island biogeography? the island that is closer to the mainland is smaller than the island that is further from the mainland. the species inhabiting the closer island reproduce more quickly. organisms are able to immigrate to the closer island due to a shorter travel distance from the mainland. conditions of the closer island are favorable for reproduction.

Explanation:

Island biogeography theory posits that closer islands to the mainland have higher species - richness because organisms can more easily immigrate due to shorter travel distances from the mainland.

Answer:

Organisms are able to immigrate to the closer island due to a shorter travel distance from the mainland.
