A bird in a forest ecosystem has a sharper beak than many other birds. Which best explains how this adaptation may help the bird survive?

• It enables the bird to dig for water.

• It increases the likelihood for the bird to obtain food.

• It increases the likelihood of the bird finding a suitable mate.

• It enables the bird to sing louder than birds with shorter beaks.
