5. Describe how ecosystems recover from a disturbance (succession).
6. Identify the characteristics of major land and transition biomes. (Biome Poster project)
7. Explain how the different levels of study in ecology reflect the types of interactions that occur in within living systems and between biotic and abiotic components of an ecosystem.
Trends down pyramid: -Increase in geographic scale -From single species to multiple species -Increasing number of ecological factors that may be influential -Decreasing certainty in results Chapter 17-The Tree of Life:1. Need for classification systems. -Organize diverse life forms and information about each category -Improve predictive powers – e.g. if you identify a new organism, better able to predict its features -Assign universally accepted name to each organism (scientific name) -Place organisms in groups with biological meaning, to explain relationships among living things 2. Binomial nomenclature Formal system of naming species of living things by giving each a name comprised of two parts – first genus (capitalized and italicized/underlined) and then species (italicized/underlined) Homo sapiens Canis familiaris Felis catus 3. Taxa & how they show evolutionary relationships between organisms Taxa– classification group
Hierarchy: Kingdom → Phylum → Class → Order → Family → Genus → Species 4. Importance of comparative biochemistry to taxonomists; sources of information used to classify organisms. -Anatomical structure -Homologies -Developing embryos -Fossil record -Biochemistry/molecular biology – DNA, proteins 5. Characteristics of the organisms belonging to each of the six kingdoms. Note: There used to be only five kingdoms; the Monerankingdom has since been divided up into two separate kingdoms – archaebacteria and eubacteraKingdom Cell Type Cell # Feeding Type Cell Wall?

Domains and how they were derived Domain – highest taxonomic rank of organisms Three-domain system: -Archaea -Bacteria -Eukarya Chapter 18-Bacteria & Viruses:textbook pages 544-565
