the role of bees is to spread pollen for the flowers to grow and the role of the humming birds is to collect necter .
Pollination
When the hummingbird flies from flower to flower some pollen falls on its head and wings. The hummingbirds gets its nectar and the flower is pollinated. It is a win/win. Hummingbirds play an important role in the pollination of flowers.
Bees take pollen from flowers and bring it back to their hive to make honey. In fact honey is not made out of pollen, the honey bees visit flowers in search of nectar produced by plants in their flowers inside the nectary glands. While sucking the nectar the bees smear anthers and pollen load is loaded on their legs. These pollen grains attached to their legs come in contact with the stigma of other flowers when the bees move from one flower to the other. Thus pollination is done by them for plants and in return of this service plants provide nectar to them.
a) wind pollination (wind) b) insect pollination (insect) c) self pollination (the flower pollinates itself)
It depends on what you define as helpful. Yes, all bees have a role in maintaining balance in their ecosystems, especially through pollination, but they are not neccesarily "helpful" to humans directly.
Bees, butterflies, moths, and other insects help pollination. Bats and hummingbirds also help pollinate some plants. This is why it is so important that humans help the pollinators by planting the best types of plants so that we have food for ourselves.

Bees are flying insects closely related to wasps and ants, and are known for their role in pollination and for producing honey and beeswax.
The almond orchards of California are pollinated by honey bees. No bees means no pollination. No pollination means no almonds. Result - economic disaster for the almond growers.
