What are the typical shape, color, and nectar content of a flower that is pollinated by a hummingbird? What are the traits of a bee-pollinated flower?
What will be an ideal response?
Hummingbird-pollinated flowers have a deep, tubular shape; red coloration; and a large amount of nectar. Bee-pollinated flowers are shallow, reflect near-UV light, and have smaller amounts of nectar. The differences in the flowers are the result of the inherent differences in the pollinators.
