Option D, 10 individuals emigrate, 4 individuals die, 14 individuals immigrate, 0 individuals are born

Explanation:

Here we will evaluate each scenario as given in option -

Scenario I - 12 individuals emigrate, 12 individuals die, 12 individuals are born, 0 individuals immigrate

Substituting the given values in the equation below, we get -

population growth = (birth rate + immigration) – (death rate + emigration)

= $(12+0)-(12 +12)\\= -12\\$

The growth is negative and this means that population is reducing

Scenario II -16 individuals emigrate, 3 individuals die, 13 individuals are born, 0 individuals immigrate

Substituting the given values in the equation below, we get -

population growth = (birth rate + immigration) – (death rate + emigration)

= $(13+0)-(16 +03)\\= -6\\$

The growth is negative and this means that population is reducing

Scenario III - 8 individuals emigrate, 0 individuals die, 20 individuals immigrate,12 individuals are born

Substituting the given values in the equation below, we get -

population growth = (birth rate + immigration) – (death rate + emigration)

= $(12+20)-(8 +0)\\= 24\\$

The growth is positive and this means that population is increasing

Scenario IV - 10 individuals emigrate, 4 individuals die, 14 individuals immigrate, 0 individuals are born

Substituting the given values in the equation below, we get -

population growth = (birth rate + immigration) – (death rate + emigration)

= $(0+14)-(10 +4)\\= 0\\$

The growth is equal to zero and this means that population is stable.

Thus, option D is correct.
