Only 10% of energy is transferred from 1 level to
the next- what is this called?
• Energy Pyramid, 10% rule
How much energy is lost as heat from one
trophic level to the next?
• 90%
Energy ___________ Nutrients ________
• Flow, Cycle
What does the term Biogeochemical mean?
• Biological, geological, and chemical cycles
Diagram the water cycle on the board. Label
all parts
Diagram the carbon cycle. Label
Whats actually moving in a food web or
chain?
• Energy?
The nutrient that limits this productivity is called
the Limiting Nutrient
• Limiting nutrient
Rate @ which producers create organic materials
• Primary Productivity
What are the 3 main elements added to fertilizers
• Nitrogen, Phosphorus, Potassium
Limiting nutrient in freshwater systems
• Phosphorus
Limiting nutrient in salt water systems
• Nitrogen
Difference between weather and climate
• Weather: daily, Climate: yearly
What is the greenhouse effect? Diagram on
board
How much colder would the planet be
without greenhouse gasses?
• 50* F
List the 4 naturally occurring green house
gasses?
• Water, nitric oxide, carbon dioxide, methane
What are CFC’s?
• Manmade compounds that deplete ozone layer
We now make HCFC’s. How are they different
from CFC’s?
• HCFC’s are not causing ozone depletion but are greenhouse gasses
3 ways heat is distributed across planet
• Ocean currents
• Wind patterns
• Latitude
What is acid rain?
• Rain with low number of pH
How is acid rain created?
• Sulfur dioxide and nitrous oxide become nitric acid and sulfuric acid in
the environment
What is competitive exclusion principle?
• No 2 species can share the same niche in same habitat;
• not enough resources
a group of critters whose absence or presence will
determine the health and productivity of an
ecosystem
• Keystone species
When 2 different species live closely together
• Symbiosis
mutualism
• both benefit
commensalism
• 1 benefits, the other is neither harmed nor benefited
parasitism
• 1 benefits, the other is harmed
