Read the following passage and answer the questions that follow. Isn’t it incredible that India’s land area is only 2.4 percent of the world’s total land area whereas its share of the global species diversity is an impressive 8-1 percent! However, in these estimates of species, prokaryotes do not figure anywhere. Biologists are always keen on collecting data with respect to species diversity observed in different regions of the world. The data collected based on the survey conducted for species richness of groups of mammals in three different regions of the world is shown in the bar graph below. Why is the species richness maximum in Region III in the bar graph?
