Question	Answer
biome	very large climatic regions that contain a number of smaller but related ecosystems within them Each location has a similar climate and inhabitants with similar adaptions
tundra	a cold and largely treeless biome that forms a continuous belt across northern North America, Europe, and Asia. It is the largest and northernmost biome, covering about one-fifth of the world's land surface.
permafrost	a permanently frozen layer of soil under the surface, characterizes the tundra.
tropical forests	occur near the equator, in the region between 23.5 degrees N and 23.5 degrees S, known as the tropics. this region includes parts of Asia.
canopy	the treetoops form a continuos layer which shades the forest floor
epiphytes	small plants living on the branches of tall trees. Includes mosses, orchids and bromeliads.
coniferous trees	bear seeds in cones and tend to be evergreen
deciduous trees	shed their leaves each year
temperate deciduous forests	trees that lose all of their leaves in the fall and regrow them each spring
taiga	South of the tundra and north of the temperate regions. A forested biome dominated by coniferous trees, such as pines, firs, and spruces.
temperate grasslands	usually form in the interior of continents, at about the same latitude as temperate diciduous forsts
savannas	tropical or temperate grasslands that have scattered decdiduous trees and shrubs. Recieve more rainfall than deserts do but less rainfall than tropical or temperate forests do.
chaparral	a biome that is dominated by dense, spiny shrubs and has scattered clumps of coniferous trees. Is characterized by mild, rainy winters an dhot, dry summers with peiodic fires.
Deserts	areas that recive an average of less than 25 cm of rainfall per year.
