A population of squirrels is preyed on by small hawks at maturity. the smaller adult squirrels can escape into burrows. the larger adult squirrels can fight off the hawks. after several generations, the squirrels in the area tend to be very small or very large. this is an example of disruptive selection. In disruptive selection, the extreme traits i.e., very small and very large sizes are favoured over intermediate trait i.e., average size.

The answer is Lionfish
are native to the tropical Pacific. There are no natural water routes of warm

Invasive species is a species that colonizes an environment
in which it is not a native species and tends to upset the natural balance of that environment. Lionfish are naturally
found in the indo-pacific, which is their
native environment. However, their presence
in the eastern United States has have threatened
the ecosystem of the region. The fish has decimated fisheries and reef
ecosystem since they also don’t have natural predators in the region. Therefore,
their population explodes unchecked.
