A researcher 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 ?

The most likely reason explaining the diversity of bumble bees in the grasslands of Arkansas is habitat diversity and ecological niches.

Grasslands can offer a variety of microhabitats and ecological niches that can support different species of bumble bees. Factors such as floral diversity, nesting sites, and availability of resources like nectar and pollen contribute to the coexistence of multiple bumble bee species. Each species may have specific adaptations and preferences, allowing them to occupy different niches within the grassland ecosystem.

The presence of various plant species, blooming periods, and nesting opportunities can create a mosaic of habitats, providing suitable conditions for different bumble bee species. This diversity is essential for the overall health and resilience of the ecosystem, as each species may play unique roles in pollination, plant interactions, and ecosystem functioning.
