Answer to Problem 1TYK
Correct answer:
The defining feature would be that the per capita growth rate is constant. The per capita growth rate does not change during the exponential growth.
Explanation of Solution
Justification/Explanation for the correct answer:
Option (b) is given that the growth rate remains constant in exponential growth. During the exponential growth, the per capita growth rate is constant, unlike the
The per capita growth rate is given as the function of “N” (population size) and “t” (time interval) and is represented as
Explanation for the incorrect answers:
Option (a) is given that the population grows quickly in exponential growth. In the exponential growth rate, the population grows rapidly; however, it is not a defining feature. So, it is incorrect.
Option (c) is given that the growth rate increases very fast over time in exponential growth. This pattern of growth can be observed in other growth graphs also like in J-shaped or sigmoid-shaped curves. This is not a defining feature of exponential growth. So, it is incorrect.
Option (d) is given that the growth rate is quite high in exponential growth. The growth rate does not increase rapidly and the growth rate is not very high. The growth occurs gradually. So, it is incorrect.
Hence, the options (a), (c), and (d) are incorrect.
Thus, the constant per capita growth rate of the populations serves as the defining feature of the exponential growth rate.
