Vocabulary acid deposition autotroph biodegradable biogeochemical cycle biological magnification biomass carnivore consumer decomposer deforestation detritus feeder energy pyramid food chain food web fossil fuel global warming greenhouse effect greenhouse gas herbivore heterotroph hydrologic cycle net primary productivity nutrient cycle omnivore primary consumer producer reservoirs secondary consumer tertiary consumer trophic level Things to Know: 1. What are the 2 basic laws that underlie ecosystem function? 2. You should be able to describe the trophic structure (or feeding relationships) in a food web or food chain and use the following terms correctly: producer, primary consumer, secondary consumer, tertiary consumer, herbivore, carnivore 3.

Unformatted text preview: 5. What are two properties of man made substances that make them dangerous and likely to undergo biological magnification? 6. Carbon cycle: You should understand how the processes of photosynthesis, respiration, and burning (fossil fuels and wood) are involved in the transfer of carbon in a terrestrial ecosystem. 7. Nitrogen cycle: You should understand how the atmospheric nitrogen is converted to nitrate and ammonia (nitrogen fixation), uptake by plants, denitrification (by denitrifying bacteria), and burning of fossil fuels are involved in the transfer of nitrogen in an ecosystem. 8. How is the phosphorus cycle different from the carbon or nitrogen cycle? 9. What are the main sources of the nitrogen oxides and sulfur dioxide that form acid deposition? 10. You should read about global warming pp. 572-577 and be familiar with all of the text material. We also cover this topic in lecture....
