Bees collect nectar and pollen from flowers. Nectar is a sweet liquid produced by plants that serves as a food source for bees. When bees visit flowers to gather nectar, they inadvertently collect pollen on their bodies, which they transfer to other flowers as they move on. This process assists in the pollination of plants, enabling them to produce seeds and fruit. Pollen serves as a protein source for bees and is essential for the growth and development of their young. Thus, bees play a crucial role in maintaining healthy ecosystems and supporting agricultural crops through their pollination activities.
