Answer 1

A. The biodiversity allows all plant communities to survive when the ecosystem experiences severe weather.

Having a diverse range of plant species in a North American grassland helps to increase its resilience to extreme weather events such as droughts, floods, and wildfires. Different plant species may have varying levels of tolerance to different environmental conditions, so a diverse community is better equipped to withstand and recover from severe weather events. This ultimately contributes to the overall sustainability of the grassland ecosystem.
