Chapter 3 Study Guide VOCABULARY TERMS • ecosystem • detritivores • macronutrients • producers • decomposers • limiting nutrient • autotrophs • gross primary productivity(GPP) • nitrogen fixation • photosynthesis • net primary productivity (NPP) • leaching • cellular respiration • biomass • disturbance • consumers • standing crop • watershed • heterotrophs • ecological efficiency • resistance • primary consumers • trophic pyramid • resilience • secondary consumers • biosphere • restoration ecology • tertiary consumers • biogeochemical cycles • intermediate disturbance hypothesis • trophic levels • hydrologic cycle • instrumental value • food chain • transpiration • intrinsic value • food web • evapotranspiration • provisions • scavengers • runoff AP TIPS One way that a teacher taught me to teach the nitrogen cycle is the mnemonic FixNAAD ANPAN, which stands for nitrogen fixation, nitrification, assimilation, ammonification, denitrification, ammonia, nitrates, proteins, ammonia, and nitrogen. It was set up like this: Process Fix- nitrogen fixation Nitrification Assimilation Ammonification Denitrification Product Ammonia Nitrates Proteins Ammonia Nitrogen FREE RESPONSE QUESTIONS FROM PREVIOUS AP EXAMS Year 2001 2003 Question 2 1 Content Creating a food web from information given in paragraph form. Designing a controlled experiment (acorn and gypsy moth production) Describe a strategy that uses integrated management. Discussing the role that leaf litter plays in forest floor ecosystem. 3 abiotic factors that would change if leaf litter disappears. How would changing abiotic factors in the forest floor relate to an exotic species being introduced to a new ecosystem. 2007 2009 4 1 Designing a controlled experiment with exotic worm species. Describe how temperature differs in Urban and Suburban areas How is the hydrologic cycle in an urban area different from rural area Nitrogen gas and inorganic fertilizers Primary and Secondary Pollution and somg 5 steps to nitrogen cycle and must explain each step in detail
