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 tomake 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.- 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- Organisms that only spend part of their life cycle as plankton are referred to as what? (Ch. 12, Section “Plankton”)o meroplankton- 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.

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 aboveo Water has greater heat capacity than lan so the ocean does not heat up as fasto Warming of the ocean is reduced by evaporation getting rid of excess heato Radiation ffrom the sun can penetrate deep in to the water distributing its energy throughout a very large masso Water has good mixing mechanism that allow heat from onearea to be transported to 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.

(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
