Which one is right for logistic model for population growth?
$I.$ Population growth rate increases as the size of population approaches the carrying capacity
$II.$ All individual have same effect on population growth
$III.$ There are unlimited natural resources
$IV.$ As population increases the competition goes on increasing
Select the correct combination
$I$ and $II$
Only $IV$
$IV$ and $III$
$I$ and $III$
The stationary phase of a population occurs when
If the mean and the median pertaining to a certain character of a population are of the same value, the following is most likely to occur
The equation of Verhulst-Pearl logistic growth is $\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left[\frac{\mathrm{K}-\mathrm{N}}{\mathrm{K}}\right]$.
From this equation, $\mathrm{K}$ indicates:
