Managing Air Pollution

Smoke and acidic gases are the primary pollutants that decrease air quality and damage ecosystems.

Which two gases are mainly responsible for causing acid rain?

What is Managing Air Pollution?

"Air pollution is the presence of substances in the atmosphere that are harmful to the health of humans and other living beings."

Question 1

What is meant by a community in ecology?

Question 2

In a stable community, the populations of all species remain relatively constant. What is this called?

Question 3

What is biodiversity?

Question 4

Which term describes the non-living conditions in a habitat, such as temperature and light intensity?

Atmospheric Pollutants

Sulfur dioxide and nitrogen oxides dissolve in rain to form acid rain.

Acid rain kills trees and makes lakes too acidic for many organisms to survive.

Particulates (smoke) can cause global dimming and respiratory problems in humans.

Exam Tip

Lichens are excellent bioindicators for air quality; different species grow depending on the sulfur levels.
