NEET Biology question

If N = population density at time t, then population density at time t+1 can be written as Nt+1 = Nt + [(A+B)] − [(C+D)]. Select the correct option for A, B, C and D.

(A)A can be mortality and B can be natality
(B)B can be immigration and C can be natality
(C)C can be mortality and D can be emigrationCorrect
(D)A can be natality and D can be emigration

Answer: (C)

Solution

In the standard population-density equation, the terms that are added (A and B) must be natality and immigration (both increase N), while the terms subtracted (C and D) must be mortality and emigration (both decrease N); option (c), which places mortality and
