The passage suggests that a semblance between a species' plumage and the food available in

a given ecological niche

A．is an evolutionary advantage because it allows the males and females of the species to forage for food more efficiently

B．is an evolutionary advantage because it tends to permit the isolation of the species population, thus increasing food supply

C．is an evolutionary advantage because it reduces the necessity for rivalry between males of different species by helping identify females

D．is an evolutionary advantage because it minimizes the amount of energy necessary for the courtship process

E．is an evolutionary advantage because it provides a marker for the species' territory, thus reducing the energy necessary for controlling the niche's food supply
