Question

Between 15% and 30% of U.S. crops require pollination by bees. Large-scale farmers usually import non-native honeybees, but a California study showed that wild bees can carry out all or most of the pollination required for some crops. Intensive agriculture results in loss of native species, but the study showed that wild areas (chaparral and oak-woodland) surrounding a farm can stabilize and enhance pollination by wild bees. These results suggest that a) a combination of native and non-native pollinators is required b) increasing community diversity improves pollination c)honeybees are better pollinators than wild bees d) wild bees are better pollinators than honeybees e) decreasing community diversity improves pollination
