Which factor does NOT affect the size of a population?
A.
New members joining the population.
B.
Members leaving the population.
C.
The death of a member of the population.
D.
The ages of members of the population.
Unlike the gain or loss of member through immigration, emigration, or death, the age of a population's members does not effect population size, meaning the correct answer is D.
Answer is D. New members would increase the population while members leaving or the death of a member decreases it but the age doesn’t affect the size.
