2 pts Question 24 What would constitute a compromise of fitness? Hummingbirds are the best pollinators of certain flowers, but bees are the best pollinators for orchids. In some hornbill species, the male helps seal the female in a tree with her nest until the young are ready to fledge. The strong, thick beak of a woodpecker helps it find insects in trees. Turtle shells provide protection but are heavy and burdensome when moving.

Which of the following is a fitness trade-off? a) Moths are the best pollinators for datura flowers, but bees are the best pollinators for orchids. b) Algal genotypes that can grow rapidly in nitrogen-limited environments are easier for predators to digest.

Hummingbirds live mostly on a diet of flower nectar, supplemented with the occasional small insects. Two species of hummingbirds are carried to an island with many lovely flowers, having a variety of nectar tube lengths and shapes but no flower-visiting birds, by a tropical storm. One hummingbird species has a shorter, straight bill, and the other has a longer, curved bill. What would you expect to happen to these hummingbirds after some time has passed? the short-billed hummingbirds will change their diet to eating insects, and the curved-bill ones will use exclusively flowers the short-billed hummingbirds will outcompete the ones with long, curved bills, and will be the species that survives the two species will coexist, with the birds with long, curved bills using nectar of flowers with long, curved tubes, and the short-billed ones using nectar of the other flowers

A population of hummingbirds is composed of individuals with short or long beaks, which they use to reach nectar inside flowers. A flowering trumpet vine that produces many deep, bell-shaped flowers is introduced to the region, resulting in fewer short-beaked and more long-beaked hummingbirds. Which of the following conditions most likely caused this shift in the hummingbird population? Hummingbird predators avoided areas where the trumpet vine grew. Hummingbirds that compete for nectar were more successful with long beaks. Hummingbirds with short beaks overproduced offspring with longer beaks. Hummingbirds starved because the trumpet vine limited the food supply.
