Blue jays are birds that live in the forest. They can have beaks of different thicknesses.

Blue jays use their beaks to get to the seeds they eat. Blue jays with thinner beaks can easily reach and eat the seeds inside pinecones. Blue jays with thicker beaks can easily open and eat seeds with hard shells.

The image below shows three possible blue jay populations.

If the environment changes to have only seeds in pinecones, which of the following blue jay populations will most likely survive?

Populations 1 and 2

Populations 2 and 3

Only population 2

All the populations
