Question

Many populations colonizing a new habitat show a logistic population growth pattern over time, as shown in the figure. In such a population, the POPULATION growth rate.

• A. Stays constant over time
• B. Increases and then reaches an asymptote
• C. Decreases over time
• D. Increases to a maximum and then decreases

Answer 1

The correct option is B Increases and then reaches an asymptote

The given image represents the population growth curve which is given by the equation of dN/dT=rN(1-N/K). Here, the growth rate increases in the log phase and then reaches a plateau. This is the phase when the N approaches to K which causes a decrease in dN/dT value and the graph reaches to an asymptote.

Thus, the correct answer is option B.
