REVIEW FOR ENV. SCIENCE FINAL 2015
*Environment, ecosystem, ecology, 5 levels of ecology (organism, population,
community, ecosystem, biosphere), biomes (large geographic areas with similar
climate), indicator species (trout in a stream)
*Population, endangered, threatened, reasons for extinction, habitat destruction
(number one cause of extinction), biodiversity, reasons to preserve biodiversity,
carrying capacity, limiting factors, matter—always conserved and never used up in
food chain
*Primary, secondary, tertiary consumers, producers, biomagnification (increase in
levels of pollutants as you move up the food chain), bioaccumulation (the build-up
of toxins in living organisms)
*Water quality, algal blooms and “dead zones” which have depleted DO, aquifer,
watershed, source of nitrates in surface water, point and non-point source
pollutants, excessive use of groundwater impacts, direction of groundwater flow,
cold vs warm water and oxygen content
*acid rain, pH of acid rain, why doesn’t the LaX area have a serious acid ppt
problem, formation of acid rain, acid rain impact on plants
*Global Climate Change, greenhouse gases, methods to stop Global Climate Change
*Soil permeability, liner of landfills, macronutrients in soil (nitrate, phosphate,
potassium), 500 years to make one inch of topsoil, terracing, contour farming, strip
farming
*Succession, selective cutting, clear cutting, shelter cutting
Essays
1. Global Climate Change—What is it and what do carbon sinks and deforestation
have to do with it?
2. Food Web
3. Energy Pyramid, 10% rule, (use food web/chain from #3)
4. Management question
5. Wastewater treatment/septic plants (purposes, also what are they important due
to population growth?)
6. Impacts (ecological and economic) of filling in (developing) wetlands
7. Population curves (logistic and exponential), carrying capacity, limiting factors
8. Two invasive or two Endangered species in Wisconsin. Be able to list two and
describe what is happening as it relates to them.
9. List two alternative energy sources and give positive and negative impacts for
each)
10. Renewable vs Nonrenewable—recognize sources as renewable or
nonrenewable.
