Bees play a critical role in ecosystems as one of the most important groups of pollinators. Pollination is the transfer of pollen plants, which is for to produce fruits seeds. As bees travel flower to flower collect nectar, pollen stick to bodies and are to plants. Many of the world's food crops, including fruits, vegetables, and nuts, depend on this process. Therefore, the health of bee populations is directly linked to agricultural productivity and the stability of natural ecosystems.
