23. Why do coral reefs display such high species diversity? (2 pt)

24. Describe two environmental parameters that display seasonal variability in Terrebonne Bay, LA. (2 pt)

a. For each variable above, explain one behavioral or biological effect these fluctuations have on resident organisms (2 pt)

25. Who would handle temperature fluctuations better, an organism living at a temperate latitude or an organism living at a polar latitude? Why? (2 pt)

26. Species in the tropics are more susceptible to the negative consequences of the warming accompanying global climate change. Why? (2 pt)
