Question

which scenario would result in a decrease in population size, or a negative population growth? use this formula: population growth = (birth rate + immigration) − (death rate + emigration) 0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate 40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate 12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate 19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate

Explanation:

Step1: Define population growth formula

$\text{population growth} = (\text{birth rate} + \text{immigration}) - (\text{death rate} + \text{emigration})$

Step2: Calculate Scenario 1

$(14 + 14) - (14 + 0) = 28 - 14 = 14$

Step3: Calculate Scenario 2

$(10 + 28) - (0 + 40) = 38 - 40 = -2$

Step4: Calculate Scenario 3

$(17 + 0) - (5 + 12) = 17 - 17 = 0$

Step5: Calculate Scenario 4

$(25 + 0) - (4 + 19) = 25 - 23 = 2$

Answer:

40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate
