A North American grassland is usually more productive when it contains diverse plant communities. How does the biodiversity of a North American grassland affect its sustainability?
A.
The biodiversity allows all plant communities to survive when the ecosystem experiences severe weather.
B.
The biodiversity prevents all plant communities from surviving when the ecosystem experiences a heat wave.
C.
The biodiversity prevents some plant communities from surviving when the ecosystem experiences consistent weather patterns.
D.
The biodiversity allows some plant communities to survive when the ecosystem experiences slightly different weather patterns.
A.
The biodiversity allows all plant communities to survive when the ecosystem experiences severe weather.
By having a diverse array of plant species in a grassland, different species are able to thrive under different environmental conditions. This resilience allows the grassland to better withstand extreme weather events such as droughts, floods, or storms, ensuring the overall sustainability of the ecosystem.
