In an ecosystem where most flowers are long and bell shaped, there are two varieties of hummingbirds, with short, beaks and birds with long beaks. What is the most likely hummingbird population composition?

Answer 1

In an ecosystem where most flowers are long and bell shaped, it is likely that the hummingbird population composition would consist of a higher proportion of birds with long beaks. Birds with long beaks would be better adapted to access the nectar of the long, bell-shaped flowers, giving them a competitive advantage over birds with short beaks. Over time, natural selection would likely favor the birds with long beaks, leading to a larger proportion of this trait within the population.
