Answer: Small organisms such as bees are essential in establishing genetic variation.
Explanation: Without small organisms, wind is the primary method used by flowering plants in reproduction. The wind carries one flower's pollen (the pollen contains the flower's genetic material and is essentially the flower's sperm) to a nearby flower where fertilization will take place. However, bees move that pollen further than the wind and transfer it to flowers far away. This means that one flower's genetic material is spread farther by bees and other organisms and increases its genetic variety.
