Explain The Relationship Between the Carrying Capacity of a Population and the Factors That Impact an Ecosystem
Increased population will result in many consequences:
• depletion of natural resources • polluted water and air • lack of space • increase of disease-causing organisms • decrease in the quality of life 3
Quality of Air: Explain How a Highly Populated Society Causes Air Pollution • One result of air pollution is global warming. • Humans cause global warming by burning the fossil fuels. • Levels of carbon dioxide are also increased by deforestation and cement production. • 4
Air Pollution Impacts Environmental Degradation •
• • •
The global atmospheric effects of air pollution include: global warming ozone depletion acid precipitation Global Warming is the increase in Earth’s average surface temperature. Ozone Depletion is the depletion of the layer that exists in the atmosphere and absorbs ultraviolet radiation from the sun. Acid Precipitation is precipitation with a pH of less than 5.0.

Air Air Pollution
includes primary pollutant s
secondary pollutants
such as
such as
volatile organic compounds
smog
which can be removed from the air by a
scrubber
which can be trapped near Earth’s surface by a
temperature inversion 6
How Can Recycling Improve Our Quality of Life?
Example: – Recycling paper = more trees = more CO2 absorbed = reduced green house gasses = reduced global warming = less polar ice caps melting = saving coastal land masses = more habitats = more biodiversity = healthier ecosystem = a healthier planet = improved quality of life for all living things.
The above example demonstrates how everything on Earth is interconnected!!!

FCAT Multiple Choice Sample Questions
Great horned owls feed on snakes and mice among other mammals. A great horned owl population is threatened when a logging company decides to harvest its forest habitat. After many years of continuous deforestation, much of the owl population has fled in search of a new forest for nesting. Which of the following scenarios in the owl's previous habitat is most likely?
A. Both the snake and mouse populations will increase B. Both the snake and mouse populations will decrease C. The mouse population will increase but the snake population will decrease D. The snake population will increase but the

FCAT Short-Response Sample Questions § The diagram below shows the relationship between three types of animals in a food chain: Worms are eaten by birds, which in turn are eaten by snakes. § If all the birds in an area died due to a new disease, what would the impact be to the local populations of worms and snakes after one month? After one year? Explain your answer.
