14689706016	4 Main Levels Ecologists Work on	Organism, Population,Community,Global	0
14689707745	Bitoic	any living thing	1
14689709068	Abiotic	non living things like the sun, rain,soil,winds	2
14689713325	How do Ocean Gyres work?	The warm water with nutrients floats up and eventually turns cold and carries oxygen back down	3
14689717664	Lake Turnover	The yearly rising and sinking of cold and warm water layers in a lake to distribute nutrients	4
14689719491	Thermocline	a gradient of temperatures	5
14689721026	Stratfication	when distinct tempature sections form	6
14689728087	Winter	Stratfication occurs and and nutrients are kept on the bottom	7
14689731048	Spring	turnover occurs and warm waters move down with oxygen when it becomes densest at 4 degrees C	8
14689732915	Summer	stratification happens again	9
14689735518	Fall	turnover occurs and warm waters move down with oxygen when it becomes densest at 4 degrees	10
14689748521	Productivity	how much biomass is created	11
14689750587	Detrirus	ocean debris made of dead organic matter	12
14689752516	plankton	small ocean organisms that supply energy to many organsisms	13
14689755961	Eustary	where freshwater and saltwater meets	14
14689757870	Wetland	an area where the soil is mostly flooded	15
14689759022	Desert	has very little perciptation and very hot tempatures ecespically in the middle of the year	16
14689761635	Tundra	Has very little perciptation and has below freezing tempatures for most of the year	17
14689768727	Grasslands	Have even percipatation and mild tempatures	18
14689770581	Rain Forest	Has a lot of perciptation in begining of the year and a consistant tempature	19
14689774625	weather	short term sunlight, rain,and atmospheric changes	20
14689776939	climate	long term weather conditions in a certian location	21
14689779821	Bio mass	total mass of organisms	22
14689779822	NPP	Net primary productivity which is the rate producers make energy -amount of energy they use = amount of energy left for other organisms	23
14689785755	Hadley Cell	At 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 deserts	24
14689791647	Cornelius Effect	the deflection of currents away from their original course as a result of Earth's rotation	25
14689795450	Why are the poles cold?	Poles are cold because sunlight hits them on an angle instead of directly	26
14689797485	Rain shadow	Air 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
14689804391	Why 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 heat	28
14689808954	Biogeography	distrubution of plants and animals.	29
14689810493	Thermus aquaticus	lives in hot springs because it has evoloved to do that way, that is its niche enviorment	30
14689810494	Niche	Full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions	31
14689813300	fitness trade-off	two traits that cannot be optimized simultaneously, an organism cannot be able to live in both extremes	32
14689817921	Wallace Line	In 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 it	33
14689819244	Exotic Species	new to an area	34
14689819245	invasive species	an exotic species who survived and reproduced	35
14689821303	Biotic factors limiting dispearl	predators, food competition,mate compititon	36
14689826332	Abiotic factors limiting dispearl	Terrain, precipitation, temperature, atm P	37
14689833813	photic zone	where life reaches organisms water	38
14689833814	aphotic zone	where life doesnt reach organsisms in water	39
14689836034	Turbididty	cloudiness of water	40
14689844507	# of Organisms vs. Temp	Bell curve where Organisms will peak at niche	41
