Options

  1. ADeaths exceeds number of births and also number of emigrants equals number of immigrants.
  2. BBirths plus number of immigrants equals number of deaths plus number of emigrants.
  3. CBirths plus number of emigrants is more than the number of deaths plus number of immigrants.
  4. DBirths plus number of immigrants is more than the sum of number of deaths and number of emigrants.

Correct answer

D. Births plus number of immigrants is more than the sum of number of deaths and number of emigrants.

Step-by-step solution

(N)(\mathrm{N}) is the population density at time t , then its density at time t+1\mathrm{t}+1 is Ntt+1=N+[(B+\mathrm{Nt}_{\mathrm{t}}+1=\mathrm{N}+[(B+\mathrm{I})−(D+E)])-(\mathrm{D}+\mathrm{E})] Population density will increase if the number of births plus the number of immigrants (B+(\mathrm{B}+\mathrm{I})) is more than the number of deaths plus the number of emigrants ( D+E)D+E).
