quiz and all quizzes will be open book You are encouraged to bring your book to class It is your responsibility to have your iClicker with you and in working order No make up quizzes will be given What are the 3 domains of life Ch 12 Section The Three Domains of Life o Eukaraya archea and bacteria What marine organism represents the vast majority of the ocean s biomass Ch 12 Section How Are Marine Organisms Classified o plankton Plankton are organisms that float Why is a copepod which can swim and propel itself through the water classified as plankton Ch 12 Section Plankton Organisms that can photosynthesize and produce their own food are called what Ch 12 Section Plankton o autotrophic Section Plankton o meroplankton Organisms that only spend part of their life cycle as plankton are referred to as what Ch 12 What are nektobenthos Ch 12 Section Benthos o Organisms that live on the bottom but can swim or crawl through the water What is the primary factor that limits life on the deep ocean floor Ch 12 Section Benthos o Sparse food supply Of Earth s total number of species why are the fewest in the marine pelagic realm Ch 12 Section How Many Marine Species Exist o Uniform condition sin in the pelanic reform Why is the surface area to volume ratio important for phytoplankton Ch 12 Section Water s Viscosity o A larger ratio provides higher resistance to sinking and less energy to stay afloat Why do most fish and marine mammals have the same torpedo like streamlined shape Ch 12 Section Water s Viscosity o The streamlined shape minimizes the energy expended to move through the water Oceanography 1001 all sections Figueroa Lecture Series Study questions for Thursday November 8 2012 Life and Marine Life This lecture will cover Chapter the rest of chapter 12 Marine Life and the Marine Environment Starting with the section on Temperature from Trujillo Thurman Essentials of Oceanography The following quiz questions are covered in the chapter sections listed The study questions below will be administered as an iClicker reading quiz during class so you must do the reading to expect to score well on the quiz You are permitted to make notes on your reading and use them during the quiz This quiz and all quizzes will be open book You are encouraged to bring your book to class It is your responsibility to have your iClicker with you and in working order No make up quizzes will be given Most fresh water fish are hypertonic meaning their body cells contain more salt than the surrounding water Since osmosis should push water into their cells why don t they explode Ch 12 Section Salinity o All of the above What is the primary difference between pelagic environment zones below the photic zone Ch 12 Section What Are Living Things and How Are They Classified o Increasing pressure with increasing depth What are the reasons the ocean has a smaller daily seasonal and annual temperature range than that experienced on land Ch 12 Section Temperature o All of the above o Water has greater heat capacity than lan so the ocean does not heat up as fast o Warming of the ocean is reduced by evaporation getting rid of excess heat o Radiation ffrom the sun can penetrate deep in to the water distributing its energy o Water has good mixing mechanism that allow heat from onearea to be transported to throughout a very large mass other areas What is the definition of eurythermal Ch 12 Section Temperature o Organisms that can tolerate large changes in temperature Freshwater fish are isotonic hypertonic or hypotonic relative to their environment Ch 12 Section Salinity o hypertonic How does water pressure change with depth Ch 12 Section Pressure o Pressure increases with depth What is the euphotic zone Ch 12 Section What are the main divisions of the marine environment o The zone where there is enough light to support photosynthesis What are the 4 biozones of the oceanic province Ch 12 Section What are the main divisions of the marine environment o Epipelagic mesopelagic bathypelagic abyssopelagic What is the neritic province Ch 12 Section What are the main divisions of the marine environment o The zone with water depths less than 200 meters What is the deepest zone of the suboceanic province Ch 12 Section Benthic Environment o The hadal zone Oceanography 1001 all sections Study questions for Tuesday 13 November 2012 Marine Production and Marine Ecology This lecture will cover Chapter 13 Biological Productivity and Energy Transfer Sections 1 2 and 3 from Trujillo Thurman Essentials of Oceanography The following quiz questions are covered in the chapter sections listed The study questions below will be administered as an iClicker reading quiz during class so you must do the reading to expect to score well on the quiz You are permitted to make notes on your reading and use them during the quiz This quiz and all quizzes will be open book You are encouraged to bring your book to class It is your responsibility to have your iClicker with you and in working order No make up quizzes will be given Biological oceanographers discuss about biomass frequently Just what is biomass Ch 13 Section What is Primary Productivity o the total mass of all organisms of a given class What is the difference between gross primary productivity and net primary productivity Ch 13 Section What Kind of Photosynthetic Marine Organisms Exist o Gross productivity is the amount of organic carbon created by photosynthesis per unit of time and net productivity is the fross mnis the amount of organic carbon sonsumed bu the photosynthesizers What are the two primary factors that control biologic productivity in the surface oceans Ch 13 Section Factors Affecting Primary Productivity o sunlight and nutrients What is the biological pump Ch 13 Section How Does Regional Productivity Vary o The removal of organic matter and nutrients from surface water to deep water through the
