The species-area relationship is a straight line described by the equation:

Which is not a reason for maximum diversity in the tropics?

Describe species-area relationships.

Match the following locations with the number of bird species found there:

Column-$I$ (Location)	Column-$II$ (Number of Bird Species)
$P$. Colombia	$I$. $56$
$Q$. New York	$II$. $105$
$R$. Greenland	$III$. $1200$
$S$. India	$IV$. $1400$
$T$. Amazonian rain forest	$V$. $1300$

Given below are two statements.
Statement $I$: There is less species biodiversity in tropical latitudes than in temperate regions.
Statement $II$: Tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable.
In the light of the above statements, choose the correct answer from the options given below.

$A$ 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?
