NEETZoologyOrganisms and Populations
How does a population grow in a habitat with limited resources?
Options
- AExponentially
- BIn a constant linear manner
- CIn phases: lag, acceleration, deceleration, and asymptote
- DRandomly
Correct answer
C. In phases: lag, acceleration, deceleration, and asymptote
Step-by-step 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 the population density reaches the carrying capacity. A plot of N in relation to time (t) results in a sigmoid curve. This type of population growth is called Verhulst-Pearl Logistic Growth (Figure 11.3) and is described by the following equation:dN/dt = rN(1-N/K)Where N = Population density at time tr = Intrinsic rate of natural increaseK = Carryi
