Which of these is given as a cause of falling bee populations?
Bees are not only producers of honey; they are also among the most important pollinators in the world. When a bee visits a flower to collect nectar, grains of pollen stick to its body and are carried to the next flower, allowing the plant to produce seeds and fruit. It is estimated that about one third of the food people eat depends on pollination by insects. In recent years, however, bee populations have fallen in many regions because of disease, loss of habitat and the use of certain chemicals on crops. Scientists urge farmers to plant wildflowers beside their fields and to reduce their use of harmful pesticides.
