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 like a 7th grader wrote it )

Answer 1

Because birds can have different beak sizes and shapes due to their genes, some will be better at cracking seeds than others. Thanks to sexual reproduction, these birds mix their genes, which can create even more variations, giving them a better chance to adapt and survive by having more individuals able to crack seeds and find food.
