Natality increases

Vedclass · Answer

(D) Population density $(N)$ is influenced by four primary factors: Natality $(B)$,Mortality $(D)$,Immigration $(I)$,and Emigration $(E)$.The formula for population density at time $t+1$ is: $N_{t+1} = N_t + [(B + I) - (D + E)]$.$1$. Natality $(B)$: Number of births in a population during a given period,which adds to the population density.$2$. Immigration $(I)$: Number of individuals of the same species that have come into the habitat from elsewhere during a given period,which adds to the population density.$3$. Mortality $(D)$: Number of deaths in a population during a given period,which reduces the population density.$4$. Emigration $(E)$: Number of individuals of the population who left the habitat and gone elsewhere during a given period,which reduces the population density.Therefore,population density increases when Natality $(B)$ or Immigration $(I)$ increases,or when Mortality $(D)$ or Emigration $(E)$ decreases.
