Vedclass · Answer

(D) Statement $I$ is correct: Birth rate and death rate are defined as per capita births and deaths in a population.Statement $II$ is correct: Individuals of a species usually live in groups or populations rather than in isolation.Statement $III$ is incorrect: Population size is a dynamic phenomenon that changes constantly due to factors like natality,mortality,immigration,and emigration.Statement $IV$ is correct: The cumulative effect of various ecological factors on population growth is ultimately reflected in changes to the population density or size.Therefore,statements $I, II,$ and $IV$ are correct.

Column-$I$	Column-$II$
$(a)$ Diapause	$(i)$ Inactive stage during summer
$(b)$ Hibernation	$(ii)$ Inactive stage during winter
$(c)$ Dormancy	$(iii)$ Temporary suspension of development
$(d)$ Aestivation	$(iv)$ Reduced metabolic state during unfavorable conditions

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