NEETZoologyOrganisms and Populations
When does the growth rate of a population following the logistic model equal zero? The logistic model is given as dN/ dt = rN (1-N/K)
Options
- AWhen N/K is exactly one
- BWhen N nears the carrying capacity of the habitat
- CWhen N/K equals zero
- DWhen death rate is greater than birth rate
Correct answer
A. When N/K is exactly one
Step-by-step solution
If both becomes equal ,then division of them becomes one 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.
