Q.Which organism plays a vital role in pollination of trees in tropical forest ?

Orchid bees are specialised, highly effective pollinators of numerous tree and orchid species in tropical rainforests.

Male orchid bees visit flowers to collect aromatic compounds used in their courtship displays, and in doing so they carry pollen between often widely-scattered tropical trees, making them keystone pollinators that help maintain the genetic connectivity and reproduction of tropical forest plant populations — a well-known example of a specialised plant-pollinator mutualism. Rhinoceros beetles are decomposers/pest species rather than pollinators, and whi …
