□Commensalism / □Eutrophication / □Open population / □Threatened
□Community / □Extinct species / □Parasitism / □Top carnivore
□Pesticide / □Trophic level

2. Pay close attention to the following concepts. Check the boxes once you have reviewed them.

□Levels of ecological organization

□Ecological interactionsecological niches, food chains and food web interactions

□Biotic relationships  Predation, symbiosis (parasitism, commensalism, mutualism) and competition

□Energy movement through the ecosystem Trophic levels, energy pyramids and calculating the

transfer of energy through the pyramid

□ Cycles:The various processes involved, the importance of recycling nutrients, any chemical reactions

involved (including reactants and products), the role of decomposers, and human impacts on the cycle: □Matter □Water □Carbon □Nitrogen

□Biodiversity and human impacts on biodiversity

□Pesticides  types of pesticides, 3 major issues with pesticides, 4 methods of reducing our dependence

on pesticides

□Bioaccumulation and biomagnification

□Conserving Biodiversity: Species at risk (levels of risk), human impacts on sustainability of biodiversity

□Populations: Important formulas, limiting factors on population sizes, carrying capacity, density-

dependent and density-independent factors

3. Re-read your class notes, bell work, activities, labs, assignments and quizzes.

4. Re-do your old quizzes, activities, lab questions and assignment questions.
