SNC 1D1 Ecology Unit Test ReviewTest Date:
You will find questions relating to the following concepts on your next Unit Test. The test will consist of multiple choice, true/false, matching and written questions.
What is Ecology ?
o Definitions (ex. ecology, ecosystem, species, community, population)
o biosphere, lithosphere, atmosphere and hydrosphere
o biotic vs. abiotic factors
o Easter Island (what happened and what can be learned from it)
o The Lorax (what happened and what can be learned from it)
Biodiversity
o what is biodiversity and it’s importance
o how is it measured? (Methods of sampling – quadrant, netting,transect,canopy fogging)
o how is it calculated? (B.I. , species richness, relative abundance)
BRING A CALCULATOR!
Species at Risk
o five levels of classification in Canada
o factors used during classification process (ex. size, diet etc.)
Movement of Energy in Food Chains
o laws of thermodynamics
o 10% rule for the movement of energy
o trophic levels
what trophic level are producers found? primary consumers? secondary
consumers?
difference between autotrophs and heterotrophs
o know how to interpret and create food webs
The Carbon Cycle
o two key processes involved (photosynthesis and cellular respiration)
o word equation for both processes
Bioamplification
o what does it mean and how is it caused?
o examples discussed in class (ex. DDT & Indian vultures, mercury in fish)
How to calculate concentrations of toxins in food chains
The Nitrogen Cycle
o where does it take place in the biosphere?
o difference between nitrogen fixation (nitrification) and denitrification
o methods of nitrogen fixation (nitrification)
o usable forms of nitrogen/non-usable forms of nitrogen
o importance of nitrogen to living things
o how does nitrogen enter the food chain?
o how does the nitrogen cycle relate to algal blooms?
The Phosphorus Cycle
o Where does it take place in the biosphere?
o Where does phosphorus originate (found)?
o how does nitrogen enter the food chain?
o how does the phosphorus cycle relate to algal blooms?
Water Quality
o bacteria count (how it is used)
o dissolved oxygen (D.O.) – amount of oxygen
What affects the D.O?
o biological oxygen demand (B.O.D) – need for oxygen
What affects the B.O.D?
o eutrophication
what is it? what causes it?
