  6. a. Which organism(s) are tertiary consumers?b. Which organisms consume the grasshopper? What trophic level do they represent?c. Use the diagram to create one simple food chain with at least three trophic levels.

  8. # 18 • Analyzing Graphs Use the graph to answer the following questions.

  9. a. Which ecosystem shown has the lowest primary productivity per square meter? Which has the highest?b. Which ecosystem shown represents the greatest percentage of Earth's total primary productivity? Which represents the least?c. Does an ecosystem's average net primary productivity match its percent of Earth's primary productivity? Explain why or why not.

  10. # 18 – analyzing graphs A. - Open ocean has the lowest primary productivity; algae beds and reefs have the highest primary productivity. B. – Open ocean has the highest % of total (net) primary productivity; algae beds and reefs have the lowest % of total primary production.

  11. # 18 continued C. – Although algae bed and reefs have a high rate of primary productivity, they do not make up a large portion of Earth; open oceans have a low rate of primary productivity, but they make up a large portion of Earth.
