Paul Ehrlich suggested the Rivet Popper Hypothesis,in which he compared an ecosystem and species to . . . . . . and . . . . . . respectively.

Statement $A$: As moving from equator to polar region,species diversity decreases.
Statement $R$: Amazon rain forest of South America has less biodiversity.

Select the correct option regarding species diversity.

In the equation $S = CA^z$,where $S =$ species richness,$A =$ area,$Z =$ slope of the line,and $C =$ $Y$-intercept. If area is on the $X$-axis and species richness is on the $Y$-axis,what will the graph of $S = CA^z$ look like?

Match the biodiversity found in the Amazonian rainforest of South America with their respective counts.

List-$I$	List-$II$
$(a)$ Plants	$(1)$ $1,25,000$
$(b)$ Mammals	$(2)$ $427$
$(c)$ Reptiles	$(3)$ $40,000$
$(d)$ Invertebrates	$(4)$ $378$

The ................ have a greater amphibian species diversity than the .......
