Aresearcher recorded eight different species of bumble bees in the grasslands of arkansas. each species is present in large numbers. which reason most likely explains the diversity of bumble bees in the grasslands ?

Bumblebees are the pollinators that are declining in numbers due to destruction of grasslands. Bumblebees require flowering plants for their growth and multiplication as these suck nectar from the flowers. The nectar is used to make honey that acts as food for the bumblebee colony. They also make their nests in the flower-rich grasslands. Thus, grasslands act as habitat for the bumblebees and this is the reason why they are found in abundance in the grasslands.
