A species of birds lives in a habitat that is experiencing an extended drought. The birds have a beak that allows them to crack open the seeds of a certain plant. However, those plants have all been killed by the drought.
Which statement describes how this species might survive and have reproductive success?
A. Birds will mature faster and lay more eggs to ensure that they have more offspring.
B. Birds will compete with other species that have an abundant food source not affected by the drought.
C. Birds with a trait that allows them to feed on a different food source will pass the trait to their offspring.
D. Birds' beaks will change during the course of the bird's lifetime and they will survive by eating a different type of food.
