An example of mutualism between plants and insect pollinators will be:
| 1. | Bees pollinate flowers while obtaining nectar, which is their food source. |
| 2. | Flowers provide shelter to insects, and insects provide nothing in return. |
| 3. | Insects eat parts of the flower, which helps the plant reproduce. |
| 4. | Plants capture and digest insects to obtain nutrients. |
