The best explanation for the difference in beak shape between the small insectivorous tree finch and the large ground finch is: B. The two different finches have adapted to eating different food available to them. This difference in beak shape is a classic example of adaptive radiation, where closely related species evolve different traits to exploit different food sources within the same environment. In the case of the tree finch and ground finch, their beak shapes have adapted to the specific types of food they consume. For example, the tree finch's beak may be more suited for capturing insects in trees, while the ground finch's beak may be better for cracking seeds on the ground. This adaptation in beak shape allows each finch species to effectively feed on the food sources available to them in their respective habitats. By specializing in different food sources, these finches can reduce competition between species and thrive in their unique ecological niches.
