Answer 1

The most likely keystone species among the predators listed is the mountain lion. Keystone species are those that have a disproportionately large effect on their environment relative to their abundance. Mountain lions are apex predators and help regulate the populations of other species, which in turn maintains the balance of the ecosystem.
