Question

The per capita birth (b) and death (d) rates are measured for two populations across a range of population sizes in the attached figure. The equation for exponential growth rate is dN/dt=rN where the per capita growth rate is r=(b-d). The equation for logistic population growth rate is dN/dt=rN(1-N/K). With logistic growth, r varies as a function of the population size with density-dependent birth and/or death rates. See attached image

If the death rate decreased, what would happen to the population trajectory for population A?

a) increase faster

b) increase slower

c) decrease faster

d) decrease slower
