Question

by tracking births, deaths, immigrants, and emigrants, scientists can measure population growth. population growth = (births + immigrants) - (deaths + emigrants) imagine a population of 11 chickens (1 rooster and 10 hens) living on a farm. over the course of one month, 20 new chicks were born into the flock, 3 of which died. the farmer added 1 new hen to the flock. what was the population growth over this month - long period? chickens

Explanation:

Step1: Identify values

Births = 20, Deaths = 3, Immigrants = 1, Emigrants = 0

Step2: Apply population - growth formula

Population growth=(Births + Immigrants)-(Deaths + Emigrants)=(20 + 1)-(3+0)

Step3: Calculate the result

(20 + 1)-(3+0)=21 - 3=18

Answer:

18
