The relationship between species richness and ecosystem stability is characterized by the idea that diverse ecosystems tend to be more resilient. Greater species richness can enhance ecosystem productivity, stability, and functionality, allowing ecosystems to better withstand disturbances such as climate change, invasive species, or habitat loss. Diverse interactions among species can lead to more effective resource utilization and nutrient cycling. Conversely, reduced species richness can make ecosystems more vulnerable to disruptions. Thus, preserving biodiversity is essential for maintaining ecological balance and resilience.
