Document Summary
Scientific method science means to know ask questions and then attempt to find answers example: macarther: study of warblers, question: how can several species of insect eating warblers live in the same forest without one species eventually excluding the others through competition, hypothesis : several warbler species are able to coexist because each species feeds on insects living in different zones within trees, determine validity by testing predictions that follow from the hypothesis, test by observation, experiment, and modeling. What nutrients contribute to amplified eutrophication: test in field apply different combinations of different nutrients to various sections of lakes and observe, must test in field rather than in a lab because of several factors, underlying mechanisms driving ecological shift require the ability of microflora and fauna to shift in species composition as nutrient levels shift, exchange of nitrogen and carbon with the atmosphere cannot be reproduced in lab, determined that phosphorus was primarily responsible for amplified eutrophication.
