The primary function of grasslands in ecosystems is to support a diverse range of plant and animal life while maintaining overall environmental health. Grasslands act as major sinks for carbon dioxide, helping to mitigate climate change, and they play a critical role in soil health, preventing erosion and enhancing water retention. They provide essential habitats for numerous species and are crucial for livestock grazing, which can contribute to rural economies. Grasslands also influence local weather patterns, highlighting their significance in both biodiversity conservation and agricultural productivity.
