Read the following passage carefully and answer the questions given below.

There are over 20,000 bee species and together they help pollinate more than 75% of the world’s leading food crops. Honeybees tend to hog the
limelight, but few realise how important diversity is to this process. Having lots of different species of pollinating insects on farmland can lead to
better crop yields, while crops attended by fewer species tend to set less fruit and produce fewer seeds.
Providing ample opportunities for a diverse range of insects to nest and forage on farms over long periods of time could make pollinator
communities more diverse and abundant. It may help keep pollination stable over several years too. That could mean mowing grass or pruning
hedgerows less often and planting wildflower strips alongside crops. Since many pollinators, particularly bees, nest in soil, allowing room for
bare ground and dead wood and limiting the use of agrochemicals could also make farmland habitats more attractive to a wide range of species.
We also found that if a particular species of solitary bee, bumblebee or honeybee was the most numerous on a patch of farmland throughout all
the years of the study, the overall number of pollinators was more stable too. A previous study found that a small minority of dominant species
often carries out the majority of crop pollination.
So, a short-term fix might be supporting the same dominant species from one year to the next. This could be achieved using managed pollinators,
such as honeybees or bumblebees. But this is not a sustainable solution. In the long term, farms with just a handful of pollinator species should
focus on boosting the diversity of their pollinator community.
While a few dominant species play an important role in pollinating crops at present, rebuilding the diversity of wild pollinators offers insurance
against future changes in the environment. If one dominant pollinator struggled to cope with rising temperatures or a disease outbreak, a diverse
community of other species could take over and prevent a collapse in crop pollination.
