Plant diversity positively impacts ecosystem function by enhancing resilience, nutrient cycling, and productivity. Diverse plant communities can better withstand environmental stressors, such as droughts and diseases, by providing a variety of responses to challenges. Moreover, different plant species contribute to nutrient and water dynamics, supporting a more stable ecosystem. High plant diversity also supports various animal species, promoting overall biodiversity and ecosystem services like pollination and soil health. This interconnectedness highlights the essential role of plant diversity in maintaining ecological integrity.
