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)
A.0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate
B.40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate
C.12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate
D.19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate

Answer 1

the person above me is right, the answer is b

Step-by-step explanation:

Answer 2

The correct answer is option B.

Step-by-step explanation:

Using Formula:

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

A) Birth rate = 14

Immigration = 14

Death rate = 14

Emigration = 0

Population growth = (14 + 14) – (14 + 0)= 14

B) Birth rate = 10

Immigration = 28

Death rate = 0

Emigration = 40

Population growth = (10 + 28) – (0 + 40)= -2

C) Birth rate = 17

Immigration = 0

Death rate = 5

Emigration = 12

Population growth = (17 + 0) – (5 + 12)= 0

D) Birth rate = 25

Immigration = 0

Death rate = 4

Emigration = 19

Population growth = (25 + 0) – (4 + 19)= 2

Scenario (B) would result in a decrease in population size, or a negative population growth.
