1) What are the three main groups of primary producers in the oceans? 

2. How do latitude, depth, and the seasons affect primary productivity? 

3. Describe and graph the patterns of primary productivity through the seasons in the temperate, polar and topical regions? How many phytoplankton blooms do each of these regions have? How do light and nutrient levels change through the seasons in each of these regions? When does the water column become stratified in each of these regions and how does it affect primary productivity? 

4. Identify ways in which organisms in the oceans can improve flotation. 

5. What is the swim bladder and what is its function? Understand the differences between physostomous and physoclistous swimbladders. How are each of these swim bladders inflated? 

6. Identify other things that can help with floating? What is squalene? Where is it found and what is its function? 

7. Know the differences between white and red muscle and what each of these is primarily used for? What is myoglobin? 

8. How can some tunas and sharks maintain an internal body temperature that is higher than that of the outside water? What is the rete mirabile? What is its function? How is countercurrent flow associated with its function? 

9. Describe the structure of gills in fishes and the functions of gill filaments and gill rakers. Identify ways in which the efficiency of gas exchange by the gills is improved. What is ram ventilation? 

10. Identify different anatomical modifications that make tunas more efficient at swimming. What are the aspect and fineness ratios?
