What is Eukarya Archaea and Bacteria The 3 domains of life In photosynthesis what three things must come together to produce sugar and oxygen Light Water and Carbon Dioxide What is chemosynthesis The biological process that uses chemicals such as hydrogen sulfide to combine water carbon dioxide and oxygen into carbohydrates What is an autotrophic organism An organism that can make organic matter through photosynthesis or chemosynthesis Organisms that float and cannot swim against a current are called what Plankton How does light change with depth As depth increases light decreases exponentially Which color of the visible spectrum can penetrate the ocean Blue Some organisms can generate light by themselves this ability is called what Bioluminescence A poikilotherm is an organism that does what Cannot regulate their body temperature What is the difference between a homoeotherm and an endotherm Both can regulate their body temperature but homeotherms are better at it What is osmosis Diffusion of water across a membrane What strategies or methods help an organism float All becoming smaller to increase surface area to volume ratio gas filled chambers and oil storage help an organism float 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 Oxygen What is the name of the zone that includes coastal waters Neritic The ocean environmental zone having low temperature no light and great pressure is the zone Abyssal In the ocean free floating organisms that are autotrophic are called what Phytoplankton Plankton are organisms that float Why is a copepod which can swim and propel itself through water classified as plankton Because of its small size it cannot swim very far so its location is determined by the currents What organism is responsible for the vast majority of Harmful Algal Blooms Dinoflagellates What is meroplankton Organisms that only spend part of their life cycle as plankton Which of the following are phytoplanktons Diatoms and Dinoflagellates only What is the name of the processes that convert dissolved organic matter into biomass that can be consumed by other organisms The microbial loop What is the difference between gross productivity and net productivity Gross productivity is all the organic carbon generated by photosynthesizers while Net productivity is the amount leftover after subtracting the organic carbon used by respiration In the dark light bottle experiment one of the following is measured in the dark bottle Respiration What processes does phytoplankton biomass depend on Both Growth and reproduction and Death and grazing When referring to phytoplankton biomass what is top down control Grazing by heterotrophic consumers controls the amount of phytoplankton biomass that can accumulate What is the term used to describe a single sequence of organisms through which energy is transferred Food chain What is the trophic efficiency The percent of energy passed to the next higher trophic level from the trophic level below What is a food web The feeding relationships between all organisms in an ecosystem What is a trophic pyramid At successively higher trophic levels the number of individuals and the total biomass decreases The depth at which the rate of photosynthesis equals the rate of respiration is called what Compensation depth
