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.
