3 2All 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

4 3Generally, 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

5 4Bioaccumulation can be defined as: A The amount of energy that is retained with each increasing level of the food chain is only 10% B 90% of the energy from the lower-levels of the food chain is l ost to the environment as thermal & other forms of energy C A substance building up in the tissues of organisms and increasing in toxicity up the food chain D A substance building up in the tissues of higher-level organisms & causing a toxic trickle-down effect on lower-level organisms

6 5The deep scattering layer is defined by… A The migrations of organisms through the depths to avoid salinity B The migrations of organisms through the depths to avoid sunlight C The migrations of organisms along the Great Ocean Conveyer D The scattering of organisms throughout the aphotic water column
