Question : Assertion : A population growing in a habitat with limited resources shows initially a lag phase, followed by phase of accelerated and deceleration and finally as asymptote, when the population density reaches the carrying capacity. Reason : In Verhulst-Pearl Logistic growth, plot of N (population density) at time (t) results in a sigmoid curve.

Question : Assertion : A population growing in a habitat with limited resources shows initially a lag phase, followed by phase of accelerated and deceleration and finally as asymptote, when the population density reaches the carrying capacity. Reason : In Verhulst-Pearl Logistic growth, plot of N (population density) at time (t) results in a sigmoid curve.
Answer» Solution :A population growing in a habitat with limited resources SHOWS initially a lag phase, followed by phases of acceleration and deceleration and FINALLY an asymptote, when thepopulationdenstiy reaches the carrying capacity. A plot of population density (N) in relation to time (t) results in a sigmoid CURVE. This type of population growth is called Verhulst-Pearl Logistic Growth and is described by the following equations:`(dN)/(dt)=rN((K-N)/(K))`Where N = Population density at time t r = Intrinsic rate of natural INCREASE and K = Carrying capacity.
