Using evidence from the diagram, which adaptation has allowed finches to survive in their habitat?

I would assume, from the diagram, it's their beaks.

Explanation:

Finches are largely different and reside in different areas, but the part of them that has changed is their beaks because each species eats a different type of food.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
