Answer this in one to two sentences and make it sound like a high schooler wrote it

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.

Like, there's this bird species and some birds have bigger beaks that are good for cracking seeds, and some have smaller beaks that are better for hunting bugs. But then this new species shows up and eats all the bugs, so those birds gotta rely on the seeds only now.

In one to two sentences, explain how genetic variation from sexual reproduction can save this species from extinction.

Mating between birds with varying beak sizes can lead to offspring with a mix of beak traits, increasing the chance that some individuals may have beaks better suited for cracking seeds, thus ensuring the survival of the species.

So like, there's this bird that has different beak sizes and shapes, right? Some birds with bigger beaks are good at cracking seeds, and others with narrower beaks are better at finding bugs. But then this new species shows up and eats all the bugs, leaving the birds with only seeds to eat, which totally sucks for them.

The bird species had some birds with bigger beaks that could crack seeds and others with narrower beaks that were good at finding bugs. But then a new species came and ate all the bugs, so now the birds only have seeds to eat.
