What is an age pyramid?

Options

  1. AA structure representing the physical traits of individuals in a population
  2. BA plot showing the age distribution of individuals in a population
  3. CA pyramid representing the genetic diversity within a population
  4. DA graph illustrating the behavior patterns of a population

Correct answer

B. A plot showing the age distribution of individuals in a population

Step-by-step solution

Another attribute characteristic of a population is sex ratio. An individual is either a male or a female but a population has a sex ratio (e.g., 60 percent of the population are females and 40 per cent males).
