Solution
The correct option is B Exponential Population growth curve is the graphic representation of population growth by plotting number of individuals at different time intervals. The human population growth curve is S-shaped or sigmoid. It has three phases: (a) Lag phase is slow in the beginning due to small size of population, lack of adaptation to new environment and slow development (b) Log phase or exponential phase is the geometric increase in population size due to abundance of food, space and natural resources.
(c) Stationary phase or zero growth phase is the stability of population, i.e., birth and death rates are equal, so that there is no growth in population size.
