In an ecosystem where most flowers are long and bell-shaped, the most likely hummingbird population composition would be more long-beaked hummingbirds. This is because long-beaked hummingbirds would have better access to the nectar within the long flowers, allowing them to feed more efficiently and likely leading to greater survival and reproductive success compared to short-beaked hummingbirds. Over time, natural selection would favor the long-beaked variety in this specific environment.
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.
