Answer 1

In a food web, a keystone species is one that has a disproportionately large impact on its environment and ecosystem relative to its abundance. Among the options provided, the frog is most likely to be a keystone species. Frogs often play important roles in both aquatic and terrestrial ecosystems as both predators and prey, and their presence can significantly influence the population dynamics of other species. In contrast, deer, grasshoppers, and mice may not have as strong of an ecological impact in the same way that frogs do.
