The primary function of biodiversity in supporting ecosystem services lies in its ability to enhance resilience and productivity within ecosystems. Diverse biological communities lead to more stable ecosystems that can better withstand environmental changes and stresses, such as climate change and disease outbreaks. Biodiversity contributes to essential services such as pollination, nutrient cycling, and water purification. It also supports the availability of food and medicine. Protecting biodiversity is fundamental to maintaining these ecosystem services that humans rely on for survival and overall well-being.
