(c)Logistic
Growth Model No
population can continue to grow exponentially, as the resource availability
become limiting at certain point of time. Logistic growth model have fixed
carrying capacityIt
is described by the equation Rate of change of population
densityN
= Population
density at timeN
= Population

= Carrying capacity Population
growth curve when resources are not limiting.
Plot is exponential or geometrical curve . When resources are limiting the
growth, plot is logistic is carrying capacity |
