Alligators are predators that live in the Florida Everglades. A scientist is using a computer model to determine whether the all
igator is a keystone species in the Everglades. The graph shows the population of aligators in one of the computer simulations

The simulation also provides data for many other Everglades species. Which of these results would provide the strongest evidence that the
aligator is a keystone species?
The populations of many species increase and decrease in a similar pattern as the alligator.
Explanation:
Since alligators in Florida are a keystone species, other species rely on it as well to keep everything in balance. Keystone species maintain structure, stability, and diversity in an ecosystem.
Macroevolution studies how taxonomic groups above the level of species change. Its evidence draws frequently from the fossil record and DNA comparisons to reconstruct how various organisms may be related
