1 Topic 4 Ecology Ecology Conservationist Hierarchy of life- species, population, community, ecosystem, biosphere Greenhouse gases Climate Change vs. Global warming HFCs and CFCs Charles Keeling and carbon dioxide Vocabulary – Quizlet/ Ex. Or Picture Modes of nutrition - Autotrophs, Heterotrophs, Consumers, Detritivores, Saprotrophs Trophic level Nutrient cycling Carbon cycle vs. Carbon flux Methanogenic bacteria (Archaeans) Mesocosms

2 Virtual labs Mesocosms /feature/mesocosm-lab /feature/mesocosm-lab B452/Winogradsky_columns/ wc.html B452/Winogradsky_columns/ wc.html webcontent/animations/conte nt/winogradsky.html webcontent/animations/conte nt/winogradsky.html om/sites/dl/free/ / /BL_04.html om/sites/dl/free/ / /BL_04.html (Complete journal and table) Ecosystem ci/genbio/virtual_labs_2K8/ labs/BL_21/index.html ci/genbio/virtual_labs_2K8/ labs/BL_21/index.html Orbiting Carbon Observatory-

3 Exam-style questions Which of the following statement is correct? A. A community is the place where several different species live. B. Heterotrophs are organisms that feed off organic matter. C. Decomposers bacteria are detritivores D. A habitat is a community and its abiotic environment. Which substances increase the greenhouse effect by the greatest amount? A. Nitrogen and methane B. Sulfur dioxide and nitrogen C. Methane and HFCs D. Oxygen and HFCs

4 Questions State the difference between energy movement and nutrient movement in an ecosystem. State 2 ways in which the formation of peat differs from the formation of coal. Explain what the arrows represent in a food chain. Describe what is meat by a food web. List 3 ways energy is lost when moving from 1 trophic level to the next. The leaves of a tree store 20,000 J m-2 y-1 of energy. Estimate the amount of energy stored by the caterpillar that feed on the leaves.

5 Topic 5 Evolution & Biodiversity Vocabulary & Ex/picture Variation Selection pressures Evolution Homologous structures Analogous structures Artificial selection/ Selective breeding Fossil record Adaptive radiation Natural selection Competitive advantage Charles Darwin Alfred Wallace Industrial melanism and moths

6 Classification of biodiversity Binomial system of classification 7 levels of taxonomy Carolus Linnaeus Carl Woese 4 Main phyla of plant kingdom 7 Phyla for some the animal kingdom Dichotomous key Cladogram/ Cladistics

8 Questions Define the term “clade.” If 2 organisms are member of the same order, then they are also members of the same: A.Genus B.Class C.Family D.Species Outline the role of variation in evolution.
