Format of test
Each TEAM may bring 1 piece of 8.5”x11” paper with notes in any form and 2 non-graphing calculators
Likely to be a station test
Emphasis on application of knowledge, lots of graphs, diagrams, calculating carbon footprints, reading energy labels, interpreting food webs
The Rules
Part 1 – Principles of Ecology
- Food webs
- Trophic Pyramids
- Nutrient Cycling
- Population Dynamics
- Species Diversity

Imagine this ecosystem is balanced. Fill out the following chart if:
Species Population
Cricket decreases
Duck
Grass
Snake

Nutrient Cycle
• Carbon, Nitrogen, Phosphorus, Water• Diagrams of these should be on your note sheet
What cycle is shown below?What process does #2 show?What process does #3 show?Does process #1 increase or decrease the amount of this nutrient in the atmosphere?What is another source not shown in the picture that adds this nutrient to the atmosphere?

Terrestrial Biomes
Forests, grasslands, deserts, tundra
Know climates and general species interactions in these biomes

The Rules
Part 2 – Problems results from human impact on the quality of our environment
Terrestrial Systems Desertification Deforestation Soil Pollution Waste Disposal Mining
• Population Growth Issues• Habitat Destruction• Farming Practices• Fertilizers &
Pesticides
i.e. We are really good at messing things up

Part 3: Solutions to reversing/reducing human impacts that harm our environment
Sustainability Strategies
Bioremediation Strategies
Renewable, nonrenewable & alternate energy sources
Waste Management
Legislation/Economic Opportunity (Div C only)
Definition, Take 1: Sustainability is to meet the needs of the present without compromising the ability of future generations to meet their own needs.

About 12%
FootprintsHow Many Gallons of Water is in a . . .
CarIt takes an estimated 39,090 gallons of water to make a car. It's unclear if that includes the more 2,000 gallons used to make its tires--each tire takes 518 gallons to make.
Pair of JeansIt takes around 1,800 gallons of water to grow enough cotton to produce just one pair of regular ol' blue jeans.
Single Board of Lumber5.4 gallons of water are used to grow enough wood for one lumber board.
Barrel of BeerIn order to process a single barrel of beer (32 gallons), 1,500 gallons of water are sucked down.

Example Question: Your landscaping company had been hired
to redesign the front courtyard at the Governor’s Mansion in Raleigh to include more xeriscaping. Which of the following
layouts best fits the new design requirements?
Energy Sourceshttp://energyquest.ca.gov/index.html
A little cheeseball on the graphics and sound effects, but lots of great resources. The energy story has a chapter on each kind of energy that sums it up well.

Division C only – Legislation & Economic Opportunity
Will often come from what is happening in the news
Example: United Nations Climate Change Summit in November
Rob Kendrick: Life in India’s coal mines
“Coal is a paradox. It’s a cheap and plentiful energy source that created and continues to power our modern world, yet our continued reliance on coal threatens the very world it helped create.”
