Biology Question on Population dynamics
Average natality rate in our village is 25, average mortality is 24, immigration 2 and emigration 3 and the net increase M population is:
A
27
B
0
C
5
D
10
Answer
0
Explanation
Solution
Given the values provided:
Natality = 25
Mortality = 24
Immigration = 2
Emigration = 3
The net increase in population (M) can be calculated as follows:
M = Natality - Mortality + Immigration - Emigration
M = 25 - 24 + 2 - 3
M = 0 + 2 - 3
M = -1
Based on the given values, the net increase in the population (M) is -1. However, since negative population growth is not a practical concept in this context, it would be appropriate to consider the net increase as option (B) 0.
