Alligators are predators that live in the florida everglades. a scientist is using a computer model to determine whether the alligator is a keystone species in the everglades. the graph shows the population of alligators in one of the computer simulations. the graph shows the population of alligators in a computer simulation. the population holds steady for the first two years, drops from 100 percent to 70 percent between year 2 and year 4, and drops from 70 percent in year 4 to 10 percent in year 6. the population reaches its low point in year 8, at 8 percent. then it begins rising again, to 12 percent in year 10, 20 percent in year 12, 36 percent in year 14, and finally, to 44 percent in year 16. the simulation also provides data for many other everglades species. which of these results would provide the strongest evidence that the alligator is a keystone species? a. the populations of many species increase and decrease in a similar pattern as the alligator. b. the populations of many species are always increasing, regardless of the changes to the alligator population. c. the populations of many species are always decreasing, regardless of the changes to the alligator population. d. the populations of other species are staying about the same, regardless of the changes to the alligator population.
