Green Generation
B/C 2016
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

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?
Nutrient Cycle
• Carbon, Nitrogen, Phosphorus, Water
• Diagrams of these should be on your note sheet
What process does #2 show?
Respiration
What process does #3 show?
decomposition
Does process #1 increase or decrease
the amount of this nutrient in the
atmosphere? decrease
What is another source not shown in
the picture that adds this nutrient to the
atmosphere? Fossil fuel combustion
Terrestrial Biomes
 Forests, grasslands, deserts, tundra
 Know climates and general species interactions in
these biomes

The Rules
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.

Footprints
How Many Gallons of Water is in a . . .
Car
It 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 Jeans
It takes around 1,800 gallons of water to grow enough cotton to produce just one pair
of regular ol' blue jeans.
Single Board of Lumber
5.4 gallons of water are used to grow enough wood for one lumber board.
Barrel of Beer
In 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 Sources
http://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.
Great data source

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.”
