14689709068Abioticnon living things like the sun, rain,soil,winds2
14689713325How do Ocean Gyres work?The warm water with nutrients floats up and eventually turns cold and carries oxygen back down3
14689717664Lake TurnoverThe yearly rising and sinking of cold and warm water layers in a lake to distribute nutrients4
14689719491Thermoclinea gradient of temperatures5
14689721026Stratficationwhen distinct tempature sections form6
14689728087WinterStratfication occurs and and nutrients are kept on the bottom7
14689731048Springturnover occurs and warm waters move down with oxygen when it becomes densest at 4 degrees C8
14689732915Summerstratification happens again9
14689735518Fallturnover occurs and warm waters move down with oxygen when it becomes densest at 4 degrees10
14689748521Productivityhow much biomass is created11
14689750587Detrirusocean debris made of dead organic matter12
14689752516planktonsmall ocean organisms that supply energy to many organsisms13
14689755961Eustarywhere freshwater and saltwater meets14
14689757870Wetlandan area where the soil is mostly flooded15
14689759022Deserthas very little perciptation and very hot tempatures ecespically in the middle of the year16
14689761635TundraHas very little perciptation and has below freezing tempatures for most of the year17
14689768727GrasslandsHave even percipatation and mild tempatures18
14689770581Rain ForestHas a lot of perciptation in begining of the year and a consistant tempature19
14689774625weathershort term sunlight, rain,and atmospheric changes20
14689776939climatelong term weather conditions in a certian location21
14689779821Bio masstotal mass of organisms22
14689779822NPPNet primary productivity which is the rate producers make energy -amount of energy they use = amount of energy left for other organisms23
14689785755Hadley CellAt equator the air is hot and has water, it goes up into space and gets cold releasing water on the equator rainforests which now have warm air again and can pick up water from the 30 degree deserts24
14689791647Cornelius Effectthe deflection of currents away from their original course as a result of Earth's rotation25
14689795450Why are the poles cold?Poles are cold because sunlight hits them on an angle instead of directly26
14689797485Rain shadowAir coming off oceans collect water and rains on the mountian as its air rises and cools and leaving areas on the other side of the mountain dry(desert)27
14689804391Why are tempatures cooler next to bodies of water?The specfic heat of water is used to control the lands tempature so by living next to a body of water you will feel cooler because the water in the body of water is absorbing your heat28
14689808954Biogeographydistrubution of plants and animals.29
14689810493Thermus aquaticuslives in hot springs because it has evoloved to do that way, that is its niche enviorment30
14689810494NicheFull range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions31
14689813300fitness trade-offtwo traits that cannot be optimized simultaneously, an organism cannot be able to live in both extremes32
14689817921Wallace LineIn sumatara there is a line that divides asian animals and australian animals because before australia broke off of that section, there was a rift where that line was which never complelty froze over and australian animals could not cross it33
14689819244Exotic Speciesnew to an area34
