Extracted text: Study Questions 1. How do ecology and environmentalism differ? In what way does environmentalism depend on the science of ecology? 2. Define the terms population, community, ecosystem, landscape, biome, and biosphere. 3. How might including the abiotic environment within the framework of the ecosystem help ecologists achieve the basic goal of understanding the interaction of organisms with their environment? 4. What is a hypothesis? What is the role of hypotheses in a higher concentration of nitrogen than do other types of seeds at the site. To test the hypothesis, the ecologist compares the large grass seeds with the other types of seeds, and the results clearly show that the large grass seeds do indeed have a much higher concentration of nitrogen. Did the ecologist prove the hypothesis to be true? Can he conclude that the birds select the larger grass seeds due to their higher concentration of nitrogen? Why or why not? 6. What is a model? What is the relationship between lıypotheses and models? 7. Given the importance of ecological research in making political and economic decisions regarding current environmental issues such as global warming, how do you think scientists should communicate uncertainties in their results to policy makers and the public? science? 5. An ecologist observes that the diet of a bird species consists primarily of large grass seeds (as opposed to smaller grass seeds or the seeds of other herbaceous plants found in the area). He hypothesizes that the birds are choosing the larger seeds because they have
