Rosehips / Birds Interaction
Rose hips are the fruit of a rose plant. After the flower is pollinated, the fruit gets bigger and seeds develope within them. Birds eat them and scatter the seeds in their droppings.
Coneflower / Bee Interaction
The coneflower makes nectar that attracts the bee. The bee drinks the nectar and its legs get covered with pollen. Then it takes the pollen and pollinates another coneflower which helps the plant reproduce.
Hummingbird / Hibiscus Interaction
The hummingbird inserts its beak into the hibiscus flower. As it feeds on nectar, pollen sticks to its head. This pollen is carried to the next hibiscus flower and contacts the stigma, the female organ. Flowers are now pollinated and can produce seeds.
