How does species evenness contribute to ecosystem stability?
Higher species evenness can lead to greater resilience and stability in ecosystems.
True or False: A high level of genetic diversity within a species can enhance its ability to adapt to changing environments.
True
What is the significance of ecosystem diversity?
Ecosystem diversity is important for providing ecosystem services that support life, such as clean air, water, and pollination.

degradation
What role does biodiversity play in human health?
Biodiversity supports ecosystem services that are essential for food security, clean water, and disease regulation.
