14757321626	community	All the different populations that live together in an area	2
14757323909	ecosystem ecology	deal with energy flow and chemical cycling among various biotic and abiotic components	3
14757325680	landscape ecology	focuses on the exchanges of energy, materials, and organisms across multiple ecosystems	4
14757326404	precautionary principle	prevention is better than cure	5
14757342121	dispersal	the movement of organisms from one place to another	6
14757348126	why is distribution limited?	certain biotic+abiotic factors that occur in one area may not occur in another. temperature, water, sun, wind, soil	7
14757358262	macroclimate	Patterns on the global, regional and local level.	8
14757359114	Microclimate	The climate of a very small area, like under a log	9
14757363090	Oceans and large lakes moderate climate because...	water evaporates during the day and cools the air at night	10
14757366266	lake turnover	The yearly rising and sinking of cold and warm water layers in a lake	11
14757367062	thermocline	a layer in a large body of water, such as a lake, that sharply separates different water temperatures	12
14757370199	photic zone	upper layer of the oceans where the sun shines	13
14757372121	aphotic zone	layer of the oceans below the photic zone where no light shines	14
14757373337	detritus	Dead organic matter	15
14757373338	Benthos	organisms that live attached to or near the ocean floor	16
14757374048	benthic zone	the muddy bottom of a lake, pond, or ocean	17
14757376334	wetland	an ecosystem in which water either covers the soil or is present at or near the surface for at least part of the year	18
14757377184	oligotrophic lake	A nutrient-poor, clear, deep lake with minimum phytoplankton. (like Adirondacks lake)	19
14757379345	eutrophic lake	Lake with a large or excessive supply of plant nutrients, mostly nitrates and phosphates (like LGC)	20
14757383196	littoral zone	the shallow zone of soil and water in lakes and ponds where most algae and emergent plants grow	21
14757383981	limnetic zone	a zone of open water in lakes and ponds farther from shore	22
14757393839	Estuary	where river meets ocean	23
14757395872	intertidal zone	the area of shoreline revealed between low and high tides	24
14757396912	Oceanic Palegic Zone	open ocean	25
14757397693	coral reef	The most diverse marine biome on Earth, found in warm, shallow waters beyond the shoreline.	26
14757398435	marine benthic zone	ocean floor, near deep sea vents	27
14757400669	Climograph	A plot of the temperature and precipitation in a particular region.	28
14757401338	canopy	Dense covering formed by the leafy tops of tall rain forest trees	29
14757402575	ecotone	The transition from one type of habitat or ecosystem to another, such as the transition from a forest to a grassland.	30
14757402576	tropical rainforest	lots of rain, lots of species, humans are killing it	31
14757410911	desert	An extremely dry area with little water and few plant	32
14757412416	savanna	warm year round, distinct wet/dry seasons, large mammals, scattered trees and other plants	33
14757418052	Chaparral	A biome of dense, spiny evergreen shrubs and small trees found at midlatitudes along coasts; mild, rainy winters and long, hot, dry summers.	34
14757423422	temperate grassland	a biome that is dominated by grasses, has few trees, and is characterized by cold winters and rainfall that is intermediate between that of a forest and a desert	35
14757425644	coniferous forest	a biome characterized by conifers, cone-bearing evergreen trees	36
14757428178	temperate broadleaf forest	a biome located throughout midlatitude regions where there is sufficient moisture to support the growth of large, broadleaf deciduous trees	37
14757428766	tundra	cold and dry. artic	38
