As we move from the equator towards the poles,species diversity $.........$.

There is greater biodiversity in tropical/subtropical regions than in temperate regions. Explain.

New York at $41^o\, N$ has .......... species and Greenland at $71^o\, N$ has ......... species.

For which of the following will the slope of the $Z$ line be steeper?

Select the incorrect statement with respect to greater biological diversity in the tropics.

$A$ species-area curve is drawn by plotting the number of species against the area. Why is the slope of the regression line steeper when a very large area (like an entire continent) is considered compared to smaller areas?
