During normal climatic conditions with regular rainfall, the average beak depth for a population of finches was 6.8mm. researchers found that after a drought, average beak depth increased to 8.8mm. birds with deep beaks (> 9mm) were better able to eat large, hard seeds. small hard seeds were also available after the drought, but could only be eaten by birds with shallow beaks (< 7mm). choose the graphical representation and term that best represents what would happen in the post-drought finch population if both types of seeds continue to be available.
