(i) It comprises the lag phase, exponential phase and stationary phase. (i) It comprises only two phases - lag phase and exponential phase.
(ii) Population becomes stable with zero growth rate and the curve levels. (ii) Population faces mass mortality, and the curve stops.
(iii) It is observed by most species including humans. (iii) It is observed in few organisms such as reindeer and annual plants.
