Which regions in India are rich in biodiversity and why?

Several regions in India are rich in biodiversity due to their unique climatic conditions, varied topography, and ecological complexity. The Western Ghats are known for high rainfall, dense forests, and a large number of endemic species. The Eastern Himalayas support diverse flora and fauna due to variations in altitude and climate. The Indo Burma region in northeastern India is rich in species diversity because of its tropical climate and complex ecosystems. The Sundarbans, with their mangrove forests, support unique wildlife adapted to coastal conditions. These regions provide favorable habitats, ecological niches, and evolutionary isolation, which contribute to high species richness and biodiversity,
