उत्तर
- Biodiversity maintains ecosystem health, functions, and resilience. Complex ecosystems with diverse species perform essential ecological services such as photosynthesis, oxygen production, nutrient cycling, soil fertility, pest control, and water regulation.
- Diverse ecosystems help stabilize communities, reduce year-to-year variation in productivity, and increase resilience against environmental changes or disasters. This ecological stability safeguards human well-being.
- Ecosystem services provided by biodiversity include pollination of crops, seed dispersal, climate regulation, water purification, and waste recycling, which are fundamental for survival and sustainability.
- Conservation of biodiversity in natural habitats like forests, reserves, or wetlands preserves these ecosystem functions, thereby ensuring ecological security.
