Explanation / Answer

"There is no significant difference in pollination effectiveness of honey bee and non-bee pollinators"

Reason:

The total pollination effectiveness is calculated as the product of visitation frequency and pollen deposition or fruit set per visit. From the data given, the visitation rates of non- bee are very high when compared to visitation rates of honey bee. In contrast, the per- visit pollen deposition or fruit set was significantly lower for non- bees when compared to honey bees. Thus, non- bees’ higher visitation frequency and lower per visit effectiveness were compensatory, resulting in levels of pollination- service delivery similar to that provided by bees.
