Which major biome of India is represented in the given figure?

Which of the following levels is not conceptual in terms of size?

Match List $I$ with List $II$.

$A$. Natality	$I$. $\frac{dN}{dt} = rN$
$B$. Exponential growth	$II$. Death rate
$C$. Mortality	$III$. Birth rate
$D$. Logistic growth	$IV$. $\frac{dN}{dt} = rN \left[1 - \frac{N}{K}\right]$
