A hummingbird carries food to the plant. A hummingbird helps the plant reproduce. A hummingbird protects the plant from predators. A hummingbird makes the flowers produce nectar.
I gave my students this multiple choice question: Nectar is a sweet liquid that some flowering plants produce. A hummingbird drinks nectar from a flower. When a hummingbird drinks nectar, pollen from the flower sticks to the hummingbird's beak. The picture shows a hummingbird drinking nectar from a flower. Which statement explains the role of a hummingbird in the life cycle of a flowering plant?

Only one answer is correct among these 4 choices:
- A hummingbird carries food to the plant.
- A hummingbird helps the plant reproduce.
- A hummingbird protects the plant from predators.
- A hummingbird makes the flowers produce nectar.

Could you tell me which one is correct?
