Study Guide: Unit I (Ecology) Day 1 – Overview of Bio 111W Read: “Using the Study Guides and Past Exam Questions” This first chapter introduces you to the major concepts of Bio 111W (Organisms and Evolution) and its sister courses Bio 212 (Cell Biology) and 213 (Genetics). And it demonstrates one of the uses of Study Guide, by directing you to focus on those topics within the chapter relevant to Bio 111 while passing over those that you will study in Bio 212 and 213. Read: Campbell, Chapter 1 1. List, from highest to lowest, the levels of biological organization. Bio 111 will focus on Levels 1-5. i. Biosphere, ecosystem, community, population, organism 2. Define emergent property and explain how the concept relates to the hierarchy you outlined in Note 1. Then define reductionism and explain both its power and its limitations as a tool in science. Emergent property is the way complex systems arise from simple interactions. This concept relates because as you go up from the lower levels of biological organization to the higher ones, you find a growing complexity of new properties that aren’t found in the level below. Reductionism is the simplifying of complex systems. Reductionism was used in the study of DNA by the analyzing of the molecular structure of DNA and founding its function as the chemical basis of inheritance. One of its limitations nevertheless is the inability to fully comprehend a system by analyzing its smaller components alone. 3. To test your understanding of how species are classified into groups within larger groups within yet larger groups (e.g., Fig. 1.14), copy the following list of species into your notes… Spider Mosquito Cricket Bullfrog Dog Fox Lion Cow Deer E. coli (a bacterium) … then draw circles around those pairs of species that you think are most closely related, then larger circles around the smaller ones, then larger circles yet, until a single circle surrounds everything. It’s not crucial to get every circle right at this point (that comes later) but rather that you understand the concept of classifying organisms as sets within sets. Try to name some of the circles (e.g., “mammals,” “vertebrates”) that your drew. 4. Explain in what sense the diversity of life shows an underlying unity. Hint: When you drew circles for Note 3, on what basis did you group two or more species within the same circle? The diversity of life shows an underlying unity in that animal species are made up of cells often very similar. The examination of the subsystems, in particular such systems outlining areas of cellular activity and atomic structure of cells, can explain the relationship between different species. Circles drawn in note 3 were drawn relating species with similar structures with an underlying unity, eg. Mammal. 5.
