$5$Read the following passage and answer the questions that follow. Isn't it incredible that India's land area is only $\displaystyle 2 \cdot 4$ per cent of the world's total land area whereas its share of the global species diversity is an impressive $\displaystyle 8 \cdot 1$ per cent ! 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 given below : 2024_CBSE_Biology_Set_Region1_Subset_Set1_Q29_SECTION-D__p9_15

(a) Why is the species richness maximum in Region III in the bar graph ?

OR

(a) Why is the species richness minimum in Region I in the bar graph ? (b) Plants and animals do not have uniform diversity in the world but show rather uneven distribution. Mention what this kind of diversity is referred to as. (c) Why is it that prokaryotes do not have an estimated number of their species diversity as seen in plants and animals ? Explain.
