Refer to the figure. In each of the species of columbine shown, the orientation of the flowers and the length of flower spurs are associated with a particular type of pollinator (hummingbirds or hawkmoths).Columbine flowers vary in other ways as well; for example, they differ in color, and probably in odor.What experiments could you design to determine the traits that various pollinators use to distinguish among the flowers of different columbine species?
