Question

In the sigmoid growth curve given by the side, the alphabets indicate the sequence of events. Choose the correct option where the alphabet specifies the event.

• A. A = Diminishing growth, B = Exponential growth, C = Slow growth, D = Stationary growth
• B. A = Stationary phase, B = Phase of slow growth, C = Phase of rapid growth, D = Phase of diminishing growth
• C. A = Phase of slow growth, B = Phase of exponential growth, C = Phase of diminishing growth, D = Stationary phase
• D. A = Phase of rapid growth, B = Phase of diminishing growth, C = Stationary phase, D = Phase of slow growth

Answer 1

The correct option is A A = Diminishing growth, B = Exponential growth, C = Slow growth, D = Stationary growth

The following figure represents sigmoid population growth curve which is divided into three phases- exponential phase, transitional phase and plateau phase. Initially the growth starts off slowly and is fastest in the exponential phase as during this phase birth rate increases than the death rate. Further the growth starts to decline due to diseases, predation and competition. Population is zero during last phase when carrying capacity is reached which is the maximum population size which the environment can support.

Thus, the correct answer is option C.
