Final answer:
The growth rate of the population over the next 20 days will depend on various factors such as birth rate and death rate.
Step-by-step explanation:
The growth rate of the population over the next 20 days will depend on the birth rate, death rate, and other factors. If the birth rate is higher than the death rate during this period, the population will likely continue to grow, indicating an increase in the growth rate. However, if the death rate is higher than the birth rate or if the two rates are equal, the population size may either decrease or remain unchanged, resulting in a decrease or stabilization of the growth rate.
