Answer to Question 1

A population profile is a bar graph showing the number and proportion of people (males and females separately) at each age for a given population.

Answer to Question 2

Ozone is a secondary pollutant formed as a result of a reaction between nitrogen oxides and volatile organic compounds, with sunlight as the energy source to run the reaction. Other photochemical oxidants (aldehydes, ketones, PAN) are formed under the same conditions as ozone. Sulfur and nitric acids are also secondary pollutants. These chemicals are formed when sulfur dioxide or nitrogen oxides react with atmospheric moisture and oxidants such as hydroxyl.
