The ecological relationship between species diversity and ecosystem processes is crucial for maintaining a healthy environment. Higher species diversity typically enhances ecosystem productivity, resilience, and stability, allowing ecosystems to better withstand disturbances. Diverse species perform various functional roles, contributing to processes like nutrient cycling, primary production, and pollination. When species diversity declines, ecosystems may become more vulnerable to invasive species, diseases, and climate change impacts, which can disrupt these vital processes. Therefore, conserving biodiversity is essential for sustaining the ecological functions that directly support human well-being and **environmental health**.
