What accounts for the greater ecological diversity of India?

उत्तर
The greater ecological diversity on India is because of the geographical diversity in terms of varying topography, e.g., deserts, rain forests, mangroves, coral reefs, wetlands, estuaries and alpine meadows all are present in India. This results in the building of different varieties of ecosystems with greater ecological diversity.
