2. 1You collect a sample of plankton while you are travelling. You keep this jar of plankton near a window for a week & then put it in a closet for another week. The water quality is healthy through both weeks. The sample dies off while in the closet. From this basic experiment you can hypothesize that the plankton was: A phytoplankton B zooplankton C chemoautotrophic

3. 2Generally, which of the following is TRUE about phytoplankton & zooplankton A Zooplankton require sunlight and stable temperatures B Phytoplankton can be found deep within the aphotic zone of the ocean C Zooplankon are the primary source of nutrition for phytoplankton D Phytoplankton are smaller than zooplankton

4. 3Which anatomical feature prevents schooling fish from bumping into each other: A Spinous dorsal B Dorsal Line C Lateral Line D Spinous Lateral

5. 4Many squid are considered meroplanktonic. This means: A they spend a portion of thier life as bottom dwellers B they spend all of their life as floaters C they spend a portion of their life as floaters D they spend all of their life as bottom dwellers

6. 5Which of the following pictures demonstrates counter-shading A B C D

7. 6A community is made up of A a group of populations B a group of individuals C a group of organisms D a group of biomes

8. 7Asterias rubens is the scientific name for the common starfish. These can be found in many coastal waters. These organisms must be __________________ in order to survive in these waters. A eurythermal & stenohaline B eurythermal & euryhaline C stenothermal & stenohaline D stenothermal & euryhaline

9. 8Which of the following is nektonic A A barnical B A dolphin C A dungeness crab D Spirogyra (green algae)

10. 9How does a warm-water copepod differ from a cold-water copepod: A Warm-water copepods have more appendages to propel themselves through the more dense water B Warm-water copepods have multiple appendages to keep them afloat C Warm-water copepods always have a well-defined head region D Warm-water copepods are more streamline than warm-water to move through the more viscous water

11. 10Orcinus is the _________ for a killer whale. A Kingdom B Phylum C Genus D Species

12. 11In which of the following zones would you most likely find a fish with very large, but functional eyes: A epipelagic (euphotic) B mesopelagic (disphotic) C abyssal (aphotic) D bathylpelagic (aphotic)

13. 12The majority of life within an aquatic system can be found in: A the epipelagic B the benthic C the euphotic D the bathylpelagic

14. 13Which of the following fins is located on the most posterior portion of the fish: A Soft Dorsal Fin B Caudal Fin C Pectoral Fin D Pelvic Fin

15. 14Which of the following does NOT describe coastal waters: A Coastal waters are heavily used for waste disposal B Coastal waters are used heavily for commerce, fisheries, and recreation C Coastal waters have relatively constant water temperatures & salinity D Coastal waters are relatively shallow areas that join continents

16. 15All of the following are adaptations for plankton dealing with the viscosity of water EXCEPT: A Warm-water copepods have many appendages B Many plankton have a small surface area to volume ration in order to maximize the buoyant force of water C Many plankton produce a small amount of oil to help keep themselves lower in the water column D Cold-water copepods are more hydrodynamic
