Answer 1

The answer cannot be determined from the given information. A keystone species is one that has a disproportionate impact on its ecosystem, and this cannot be determined solely based on the presence of a particular animal in a food web. More information on the abundance, habitat, and ecological roles of the animals in the food web is needed to determine which one may be a keystone species.
