Question
Chapter 37, Problem 7WIO
Summary Introduction
To determine:
The look of the declining population graph. The birth rate is compared to the death rate. The look of the age structure diagram.
Introduction:
Environmental resistance is the external factors that don’t allow the population to reach the maximum rate of growth. Environmental resistance consists of predation, competition, and factors that decrease birth rates.

Shown is an age pyramid of Brazil in the year 2021. Describe its shape. What does the shape of the age pyramid tell you about their population? What can be said about the birth rates and death rates.
Using the above graph, what is the approximate percent of the population in the US and Kenya that is under the age of 15? (number order represents US, Kenya) A24,26 B12,28 C32,62 D16,36
Two stable populations employ the same fertility schedule, but different mortality schedule. In both
populations, 20% of women between exact ages 45-55 bear a
female child annually. No child bearing occurs outside this span. In population A, there is no
mortality until age 100 where all who reached age perish.
In population B, 1% of each cohort dies within each single year of age with no
survivors beyond age 100. Compute GRR, GRR and r for each population.
ii)
Determine the birth and death rate of each.
Sketch the age distribution of each.
