spectrum can penetrate the deepest in the ocean a Red b Green c Violet d Blue e All of them are correct 8 Fluorescence Some organisms can generate light by themselves this ability is called what a b Biolighting c Bioluminescence d None of the above 9 A poikilotherm is an organism that does what a Can withstand extremely cold temperatures b Cannot withstand extremely cold temperatures c Can regulate their body temperature d Cannot regulate their body temperature e None of the above 10 What is the difference between a homeotherm and an endotherm a Both can regulate their body temperature but endotherms are better at it b Both can regulate their body temperature but homeotherms as better at it c Homeotherms can regulate their body temperature but endotherms cannot d Endotherms can regulate their body temperature but homeotherms cannot e None of the above 11 What is osmosis a Diffusion of salt across a membrane b Diffusion of nutrients across a membrane c Diffusion of water across a membrane d All of the above 12 What strategies or methods help an organism float a Becoming smaller to increase surface area to volume raio b Gas filled chambers c Oil Storage d A and B only e All A B and C help an organism float 13 The following pattern describes the concentration of what In the ocean concentrations are high at the surface then decrease as you go deeper due to respiration reaching a minimum zone after which concentrations increase again a Nutrients b Carbon dioxide c Oxygen d B and C only e All of the above 14 What is the name of the zone that includes coastal waters 15 The ocean environmental zone having low temperature no light and grate pressure is the a Neritic b Oceanic c Abyssal d Benthic e Epipelagic zone a Neritic b Photic c Abyssal d Benthic Littoral e 16 In the ocean free floating organisms that are autotrophic are called what a Algae b Plants c Phytoplankton d Zooplankton e None of the above 17 Plankton are organisms that float Why is a copepod which can swim and propel itself through the water classified as plankton a b c d It lives at the surface of the ocean where plankton live It was classified as a plankton before it was known that copepods are swimmers It has a swim bladder that keeps it from sinking so it is a floater It spends part of its life floating and part swimming so it is classified as plankton because of the floating part e Because of its small size it cannot swim very fast or very far so its location is determined by currents 18 What organism is responsible for the vast majority of Harmful Algai blooms a Red Algae b Green Algae c Diatoms d Dinoflagellates e Non of the above 19 What is meroplankton a Organisms that spend their whole life cycle as plankton b Organisms that spend part of their life cycle as nekton c Organisms that only spend part of their life cycle as plankton d None of the above 20 Which of the following are phytoplankton a Diatoms b Dinoflagellates c Euphausids d A and B only e All of the above can be consumed by other organisms a Biological pump b Chemosynthesis c The microbial loop d None of the above 21 What is the name of the processes that convert dissolved organic matter into biomass that 22 What is the difference between gross productivity and net productivity a Net productivity is the amount of organic material from photo synthesizers that can be caught in a net b Net productivity is the amount of organic carbon created by photosynthesis per unit of time and gross productivity is the net minus the amount of organic carbon consumed by the photosynthesizes c Gross productivity is the total amount of organic carbon produced during a day but net productivity is the amount left over after predation by grazing organisms d Gross productivity is the amount of organic matter created in a unit time and net productivity e Gross productivity is all the organic carbon generated by photo synthesizers while Net productivity is the organic carbon leftover after subtracting the organic carbon used in their cellular respiration 23 In the dark light bottle experiment one of the following is measured in the dark bottle a Photosynthesis b Respiration c Decomposition d Photosynthesis plus respiration e Chlorophyll concentration a Growth and reproduction b Death and grazing c Boat A and B d None of the above 24 What processes does phytoplankton biomass depend on 25 When referring to phytoplankton biomass what is top down control Light from the surface controls how fast phytoplankton can grow a b Nutrients at the surface controls how fast phytoplankton can grow c Grazing by heterotrophic consumers controls the amount of phytoplankton biomass that can accumulate d All of the above 26 What is the term used to describe a single sequence of organisms through which energy is transferred a Food web b Circle of life c Food chain d Energy efficiency 27 What is trophic efficiency below d None of the above a The total amount of energy used by photosynthesis b The percent of phytoplankton consumed by zooplankton c The percent of energy passed to the next higher tropic level from the trophic level 28 What is food web a A
