Answer:
then... the frequency of different types of bird beaks will change, because... birds with beaks that are more suited to the available food are more adapted and will be more successful over time.
Step-by-step explanation:
This is linked with natural selection.
If the type of the food available changes, then the frequency of different types of bird beaks will change, because birds with beaks that are more suited to the available food are more adapted and will be more successful over time.
Evolution of beak types will be a result of the birds adapting and changing their food habits. Natural selection is the process where organisms adapt and change.
