Homework: Human Geography
Question I:
You were introduced to a number of definitions of ecology, each of which reflects how the concept of ecology has evolved. In approximately 250 to 300 words, write your own definition of ecology and defend your selection of the concepts, terms, and the words that you use. Be sure to cover the main ideas in this module.
Question II:
• Part 1:
Hint: All pieces are in module 7 and in the readings.
In this homework, you will demonstrate that you understand the basic structure of ecosystems. Select an ecosystem (e.g., boreal forest, river, coastal rain forest, marine, grasslands), and prepare a diagram that illustrates the main components of the ecosystem as well as the main processes, including: energy flow, nutrient cycling, the mineral cycle, and the water cycle.
Your diagram should use arrows and show linkages amongst the processes and components. You will submit one diagram with all the processes and components for the ecosystem that you have selected. Where possible, use the following terminology:
o respiration
o mineral store
o nutrient cycling
o water cycle
o trophic level 1, trophic level 2, trophic level 3
o photosynthesis
o decomposers
o primary producers
o secondary producers
• Part 2:
In an essay of approximately 500-750 words (two or three double-spaced pages), explain your diagram by summarizing the basic structure and elements of the ecosystem you have selected for this exercise. Your essay should clearly differentiate: (i) energy flow, mineral flow, nutrient cycling, and the water cycle; (ii) food chains and trophic levels; (iii) primary and secondary succession.
Question III:
Distinguish between biomass, gross primary productivity, and net primary productivity. Using specific examples, outline the major factors that influence productivity in terrestrial ecosystems.
Question IV:
Define and discuss five of the following terms. Write in your own words, using an example or two, in one paragraph each.
• Historical ecology
• Systems ecology
• Open systems
• Closed systems
• Urban-industrial systems
• Nutrient cycle
• Succession
• Nitrogen fixation
Question V:
"Traditional Knowledge and western scientific knowledge are more alike than different." Discuss (agree or disagree) with reference to materials you research on the Web and in journals at TRU Library. Include at least two references in addition to the course textbook and materials.
Format your homework according to the give formatting requirements:
• The answer must be using Times New Roman font (size 12), double spaced, typed, with one-inch margins on all sides.
• The response also includes a cover page containing the student's name, the title of the homework, the course title, and the date. The cover page is not included in the required page length.
