1. Define ecosystem. (Also see p. 6G)
2. Define community. (Also see p. 4G)
3. Give the extent of the habitats for hermatypic corals. (Also see fig. 17.2 and fig. 15.11 on p. 423)
4. Explain why coral reefs form only within the photic zone.
5. Discuss the factors that inhibit coral reef formation in warm waters.
6. Describe the symbiotic relationship between coral and zooxanthellae.
7. Why do corals reefs have high biological productivity? (Three reasons)
8. Describe the importance of benthic and encrusting microalgae in the coral reef ecosystem.
9. Explain why coral growth is inhibited in the lagoon. (Also see fig. 17.3)
10. Explain why the reef terrace is relatively sediment-free. (Also see fig. 17.3)
11. Explain why encrusting corals (as opposed to branching corals) dominate the reef terrace.
12. Explain how an algal ridge forms. (Also see fig. 17.3)
13. Explain the reason for coral zonation on the seaward reef face. (Also see fig. 17.3)
14. List the stresses that intertidal organisms endure.
15. Explain the reason for communities zonation in the intertidal zone. (Also see fig. 17.10)
16. Contrast the atmospheric exposures for the four intertidal zones.
17. Define supratidal zone. (Also see p. 15G)
18. Give examples of supratidal organisms in Hawai'i. (Also see figs. 17.11 and 17.12)
19. Give the advantages and disadvantages for life in the high-tide zone compared supratidal zone.
20. Use fig. 17.11 to determine which type of organisms are abundant in the high-tide zone.
21. Give a dominant predator in the middle-tide zone. (Also see fig. 17.11)
22. List several other middle-tide zone organisms. (Also see fig. 17.11)
23. List common low-tide zone organisms. (Also see fig. 17.11)
24. How do organisms protect themselves from the principle physical hazard in the low-tide zone.
25. List the variables that make each tide pool unique.
