Vedclass · Answer

(B) The population density $(N)$ changes based on four primary factors: Natality $(B)$,Mortality $(D)$,Immigration $(I)$,and Emigration $(E)$.The formula for population density at time $t+1$ is: $N_{t+1} = N_t + [(B + I) - (D + E)]$.Population density decreases when the number of individuals leaving the population exceeds the number of individuals entering it.Specifically,an increase in Mortality $(D)$ or an increase in Emigration $(E)$ leads to a decrease in population density.Therefore,option $B$ is correct as it describes factors that reduce population size.
