FODMers Learn about Pollinators

Pollinators visit flowers for nectar and pollen and when visiting flowers, they move pollen from one flower to another of the same species to produce fertile seeds.   Most flowering plants are pollinated by bats, bees, butterflies, flies, beetles, and other animals.   Plants can also be pollinated by wind and water and self-pollinate.
