Question

Hello people ~

If natality is balanced by mortality in a population at a given time, there will be a/an
(a) decrease in the population size
(b) increase in the population size
(c) zero population growth
(d) population explosion​

Answer 1

(c) zero population growth

natality - birth rate

mortality - death rate

• when birth rate and death rate are equal. the population remains constant and does not change.
• nor increase nor decrease.

For example, the birth rate in a country is 500 and death rate is 500. both balanced. 500 - 500 = 0, zero growth in population.
