Question

At the equilibrium stage of sigmoid growth curve, population size

• A. Shows minor fluctuations
• B. Remains static
• C. Shoes slow growth
• D. Declines very slowly

Answer 1

Answer: (A)

Shows minor fluctuations

Sigmoid curve is the one inn which there is an increase in growth which is slow and gradual, then there is rapid increase in growth, after which there is a decline in growth. At the stage when the births and deaths are equal, equilibrium stage is attained. At this stage, the population size shows minute fluctuations and is almost constant.

So, option A is the correct answer.
