Which one of the following regions of India has a combination of mangrove forest, evergreen forest and deciduous forest?
- ANorth Coastal Andhra Pradesh
- BSouth-West Bengal
- CSouthern Saurashtra
- DAndaman and Nicobar IslandsCorrect
Explanation
The Andaman and Nicobar Islands are unique in India due to their geographical location (tropical), island ecosystem, and diverse topography. This allows them to host a combination of different forest types:
Mangrove forests: Found extensively along the coasts, tidal creeks, and estuaries, adapting to saline and tidal conditions. Evergreen forests: Dense tropical evergreen forests dominate the islands, characterized by a multi-layered canopy and rich biodiversity, due to high rainfall and humidity. Deciduous forests: Moist deciduous forests, also known as semi-evergreen forests, are present in some areas, particularly in the northern parts of the islands, where there might be a short dry season leading to some leaf shedding. This distinct combination of these three major forest types makes the Andaman and Nicobar Islands stand out as a biodiversity hotspot compared to the other options which might have one or two, but not all three in such prominent and diverse forms.
