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.

Answer 1

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

Biodiversity in a grassland contributes to its overall resilience and productivity. Diverse plant communities have a greater chance of containing species that can withstand varying environmental conditions, such as severe weather events. This resilience helps maintain the ecosystem's stability and functionality, supporting the survival of various plant and animal species within that ecosystem.
