11. Beak Morphology

12. Beaks tell us what the bird eats and where it lives.

13. Beak Morphology Beaks tell us what the bird eats and where it lives. This helps biologists identify, classify, and track birds

14. Beak Morphology Beaks tell us what the bird eats and where it lives. This helps biologists identify, classify, and track birds The scientific idea of Form vs. Function:

15. Beak Morphology Beaks tell us what the bird eats and where it lives. This helps biologists identify, classify, and track birds The scientific idea of Form vs. Function: Form vs. function: That a shape and composition of a structure will tell us what the organism eats, where it lives, and how it lives.

This helps us compare one species vs. another.
