What is the combined effect of relief and rainfall on Western Ghats biodiversity?
Answer and explanation
Correct answer: Varied altitude and moisture create different habitats
Option A is correct. The Western Ghats have substantial variation in elevation, slope, aspect, and local rainfall. Moist winds from the Arabian Sea rise along the escarpment, producing heavy rain on windward slopes, while rain-shadow areas are comparatively drier. Changes in altitude and moisture create forests, shola grasslands, montane habitats, moist valleys, and drier transitional ecosystems within a relatively short distance. This environmental variety supports high species richness and many endemic plants and animals. Sandy plains, extensive glaciers, and coral reefs do not result from the ordinary relief-rainfall relationship of the Western Ghats.
