As we move from the equator towards the poles,the species diversity:

Match $M$ and $N$ with the species-area relationship shown in the graphic representation below and choose the correct option.

Match the correct pair.

Column $- I$	Column $- II$ (Bird species)
$(a)$ Colombia	$(p)\; 1200$
$(b)$ $41^o N$ New York	$(q)\; 1400$
$(c)$ India	$(r)\; 105$
$(d)$ Greenland at $71^o N$	$(s)\; 56$

What is the significance of the slope of regression in a species-area relationship?

Species diversity is higher at lower altitudes than at higher altitudes because at higher altitudes:

Choose the incorrect sentence$(s)$ regarding latitudinal gradients.
$(I)$ Biodiversity throughout the world shows uneven distribution.
$(II)$ According to latitudinal gradient,there is no major difference in biodiversity.
$(III)$ Species diversity increases as we move away from the equator towards the poles.
$(IV)$ Biodiversity increases as we move from temperate to tropical regions.
