Genetic variation from sexual reproduction can enhance the adaptability of the bird species by increasing the likelihood that some individuals will possess traits, such as larger beaks, that are more suited for cracking seeds. This variation may lead to a greater ability to survive and reproduce in the changed environment, ultimately helping the species to thrive despite the loss of their original food source.
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.

Genetic variation from sexual reproduction helps the bird species by mixing their traits, so some birds might have bigger beaks that are better at cracking seeds. This way, even though they lost their bug food, some birds might still survive and grow healthy by eating seeds, which can help keep their species from going extinct.
Genetic variation from sexual reproduction gives some birds bigger beaks, allowing them to crack seeds better. This helps them survive despite losing their bug food and can prevent extinction.
Genetic variation from sexual reproduction allows some birds to have bigger beaks, which makes it easier for them to crack seeds. Since their bug food is gone, these birds can survive by eating seeds, helping the species adapt and avoid extinction.
