Question

Presently human population is following which of these trends?

• A. Sigmoid
• B. J
• C. Stagnant
• D. None of the above

Answer 1

The correct option is A Sigmoid

Presently population is increasing with high rate due to better medical facilities and food availability and thus causes exponential growth which is shown by the sigmoid curve. Whereas J-curve is seen in populations which have precise survival limits and unfavorable changes as the accumulation of toxic wastes or scarcity of food will kill individuals quickly and the stagnant curve does not show population change.

Thus, the correct answer is option A.
