Interactions in Animals

Bees gather nectar from flowers. Bees then spread the pollen from one flower to another flower, helping the plants reproduce. What kind of symbiotic relationship do the bees and flowers have?

• parasitism; the bees harm the flowers by getting nectar

• commensalism; the bees get nectar but the flowers are not affected

• mutualism; the bees get nectar and the flowers get to reproduce

• competition; the bees compete for space with flowers
