Question

A species of bird has slight variations in its beak size and shape. Some individuals with bigger beaks are better at cracking seeds. Some individuals with narrower beaks are better at hunting for bugs. An invasive species is introduced that hunts all of the bug population, wiping out that food source for the birds, so all they are left with is seeds.
In one to two sentences, explain how genetic variation from sexual reproduction can save this species from extinction make it short write it like a 4th grader 2 sentences max make them short

Answer 1

The birds that have bigger beaks can crack seeds better when bugs are gone. Because of different beak sizes, some birds can still find food and survive, helping the species not to die out.
