Define and give an example of organismal, population and community ecology a. Organismal ecology includes the study of the number of individuals in an area as well as how and why population size changes over time, such as a study of the drop in antelope population. Population ecology includes the study of adaptations that enable individuals to live in specific habitats, such as a study of the use of opposable thumbs. Community ecology includes the study of the processes and consequences of interactions within and among different species in an area, such as a study of interactions between wolves and deer. b.

A Visit to Santa. You decide to visit Santa Claus at the north pole to put in a good word about your splendid behavior throughout the year. While there, you notice that the elf Sneezy, when hanging from a rope, produces a tension of 395.0 N in the rope. If Sneezy hangs from a similar rope while delivering presents at the earth's equator, what will the tension in it be? (Recall that the earth is rotating about an axis through its north and south poles.) Consult Appendix F and start with a free-body diagram of Sneezy at the equator.

What is another question you might pose to learn more about the structural features that allow for the capture, storage, and use of free energy by archaean methanogens? a. Do archaean methanogens differ from other Archaea structurally, and if so, in what way? Is one or more of these structural differences related to these methanogens' ability to use $\mathrm{H}_{2}$ to oxidize $\mathrm{CO}_{2} ?$ b. Do archaean methanogens differ from other Bacteria structurally, and if so, in what way? Is one or more of these structural differences related to these methagens' ability to use $\mathrm{CO}_{2}$ to oxidize $\mathrm{H}_{2} ?$ c. Do archaean methanogens differ from other Archaea structurally, and if so, in what way? Is one or more of these structural differences related to these methagens' ability to use $\mathrm{CO}_{2}$ to oxidize $\mathrm{H}_{2}$ ? d. Do archaean methanogens differ from other Archaea structurally, and if so, in what way?
