Which scenario would result in a decrease in population size, or a negative population growth?
wariber [46]

40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate would result in decrease in population showing negative population growth.

Explanation:

Negtaive population growth is a term used when individuals leaving the population is more than new individuals in the population.

Individuals would leave the population by two means:

either they die or emigrate from other places to join in.

The following scenario will be analysed by the formula provided to know the negative growth in population:

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

putting the values in the equation:

first case:

immigrated individual = 14

emigrants = 0

new born = 14

died = 14

population growth = (14+14)-(14-0)= 14

second case:

immigrants = 28

emigrants = 40

new born = 10

died = 0

population growth= (10+28)-(0+40)= - 2

third case:

immigrants = 0                                                

emigrants = 12

new born = 17

died = 5

population growth = (17 +0)-(5+12) = 0

fourth case:

immigrants = 0                                                

emigrants = 19

new born = 25

died = 4

population growth:(25+0) - (19+4) =3

In second case the population growth has become negative. The value of population growth is -2.
