Read the passage below before answering the question.
The Silent Pollinators
(1) When people hear the word 'pollinator,' most picture a honeybee. Yet honeybees are only one piece of the pollination puzzle. In Oregon's Willamette Valley, native mason bees, syrphid flies, and even certain beetles do critical work transferring pollen among berry blossoms and orchard trees. Researchers at Oregon State University have found that some native species pollinate crops more efficiently than honeybees in cool, wet weather.
(2) Unlike honeybees, which live in large colonies, mason bees are solitary. Each female builds her own nest in hollow stems or wooden tunnels, provisioning each cell with pollen and a single egg. Because they do not have a hive to defend, mason bees are gentle and rarely sting.
(3) Unfortunately, native pollinator populations are declining. Habitat loss, pesticide exposure, and climate shifts all contribute. Scientists urge farmers and gardeners to plant native flowers, reduce pesticide use, and leave bare patches of soil for ground-nesting bees. Protecting these unsung pollinators, they argue, is essential to food security.
