Explain The Relationship Between theCarrying Capacity of a Population andthe 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

4

Carrying Capacity is the number of animalsan area (land or water) can supportthroughout a year without causing damageto the animals or habitat.

Quality of Air: Explain How aHighly Populated Society Causes

Air Pollution

One result of air pollution is global warming.

Humans cause global warming by burning the fossilfuels.

Levels of carbon dioxide are also increased bydeforestation and cement production.

Air Pollution andEnvironmental Degradation

Air pollution affects the following: Global Warming is the increase in Earths average

surface temperature.

Ozone Depletion is the depletion of the layer thatexists in the atmosphere and absorbs ultravioletradiation from the sun.

Acid Precipitation is precipitation with a pH of lessthan 5.0.

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 capsmelting = saving coastal land masses = morehabitats = more biodiversity = healthierecosystem = a healthier planet = improvedquality of life for all living things.

The above exampledemonstrates how everything

on Earth is interconnected!!! 10

Changes to an Ecosystem

Primary successionis a type of succession that occurs on a surface where no ecosystem existed before. It begins in an area that previously didnot support life.

can occur on rocks, cliffs, or sand dunes

Secondary successionoccurs on

a surface where an ecosystem has

previously existed. It is the process

by which one community replaces

another community that has been

partially or totally destroyed by

humans, animals, or by natural

processes such as storms,

hurricanes, floods, earthquakes, or

volcanic eruptions.

FCAT Multiple ChoiceSample QuestionsScientists are studying the relationship between the amount ofrainfall and reported cases of malaria, a disease, that is spread bymosquitoes. The scientists' data are shown in the table below. Basedon the data, what conclusion can be made?

12

A. Malaria cases increase as rainfall amounts decrease.B. Mosquito breeding increases with the amount of rainfall.C. Greater amounts of rainfall cause mosquito breeding to

decrease.D. Malaria cases decrease as the population of mosquitoes

increases.

FCAT Multiple ChoiceSample QuestionsGreat horned owls feed on snakes and mice among othermammals. A great horned owl population is threatenedwhen a logging company decides to harvest its foresthabitat. After many years of continuous deforestation,much of the owl population has fled in search of a newforest 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 mousepopulation will decrease

FCAT Short-Response Sample

Questions The diagram below shows the relationshipbetween three types of animals in a food chain:Worms are eaten by birds, which in turn are eatenby snakes.

If all the birds in an area died due to a newdisease, what would the impact be to the localpopulations of worms and snakes after one month?After one year? Explain your answer.
