Population Density

Draw and expl...

Question

Draw and explain a logistic curve for a population of density (N) at time (t) whose intrinsic rate of natural increase is (r) and carrying capacity (k).

Open in App

Solution

Here N is population density, t is time and K is carrying capacity .
If the sources are unlimited then the growth pattern is geomertic as shown in the diagram. The curve is J shaped.
r is calculated by the formula: dN/dt= rN

Q. Assertion :A population growing in a habitat with limited resources shows shows initially a lag phase, followed by phase of acceleration 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.
