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. 5 grades words

Genetic variation from sexual reproduction creates different traits in baby birds, giving them a better chance to adapt to eating seeds if their beak size or shape changes. This diversity helps some birds survive and reproduce, keeping the species alive despite the loss of their bug food source.
