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

A. only long-beaked hummingbirds
B. more short-beaked hummingbirds
C. more long-beaked hummingbirds
D. only short-beaked hummingbirds

C. more long-beaked hummingbirds

The most likely hummingbird population composition would be more long-beaked hummingbirds since the flowers are long and bell-shaped. Long-beaked hummingbirds would have an advantage in accessing the nectar of these flowers, leading to a higher population of this particular variety.
