very large terrestrial ecosystems that contain a number of smaller but related ecosystems within them.

cold and largely treeless biome that forms a continuous belt across northern North America, Europe, and Asia- largest and northernmost biome, covering 1/5 of the world's land surface.

permanently frozen layer of soil under the surface of a tundra

located near the equator, between 23.5 N and 23.5 S (the tropics) includes parts of Asia, Africa, South/ Central America. only have 2 seasons- wet or dry.

continuous layer of treetops which shades the forest floor

characterization for plants like mosses, orchids, and bromeliads. non-parasitic/autotrophs, use support from other organisms

bear seeds in cones, tend to be evergreen

temperate deciduous forest

trees that lose all of their leavese in the fall and regrow them each spring. stretch across eastern North America, Europe, parts of Asia/ Southern Hemisphere

dominated by coniferous trees, south of tundra and north of temperate regions, "boreal forest", stretches across large areas of northern Europe, Asia, and North America between 50 N and 60 N

usually form in the interior of continents, about the same latitude as temperate deciduous forests. rich and fertile soil but too dry to rain much or support trees.

tropical or temperate grasslands that have scattered deciduous trees and shrubs. supports lots of herbivores. Africa, Australia, South America. rainfall= desert< savanna< tropical/ temperate forest

dominated by dense, spiny shrubs and has scattered clumps of coniferous trees. mild, rainy winters and hot, dry summers w/ periodic fires. located in middle latitudes, about 30 north and south of equator. found primarily in coastal regions.

receive less than an average odf 25 cm of rain each year. mostly humid and hot, some can have cool winters. temperatures fall rapidly at night.

term	definition
biome	very large terrestrial ecosystems that contain a number of smaller but related ecosystems within them.
tundra	cold and largely treeless biome that forms a continuous belt across northern North America, Europe, and Asia- largest and northernmost biome, covering 1/5 of the world's land surface.
permafrost	permanently frozen layer of soil under the surface of a tundra
tropical forest	located near the equator, between 23.5 N and 23.5 S (the tropics) includes parts of Asia, Africa, South/ Central America. only have 2 seasons- wet or dry.
canopy	continuous layer of treetops which shades the forest floor
epiphyte	characterization for plants like mosses, orchids, and bromeliads. non-parasitic/autotrophs, use support from other organisms
coniferous tree	bear seeds in cones, tend to be evergreen
deciduous tree	shed their leaves each year
temperate deciduous forest	trees that lose all of their leavese in the fall and regrow them each spring. stretch across eastern North America, Europe, parts of Asia/ Southern Hemisphere
taiga	dominated by coniferous trees, south of tundra and north of temperate regions, "boreal forest", stretches across large areas of northern Europe, Asia, and North America between 50 N and 60 N
temperate grassland	usually form in the interior of continents, about the same latitude as temperate deciduous forests. rich and fertile soil but too dry to rain much or support trees.
savanna	tropical or temperate grasslands that have scattered deciduous trees and shrubs. supports lots of herbivores. Africa, Australia, South America. rainfall= desert< savanna< tropical/ temperate forest
chaparral	dominated by dense, spiny shrubs and has scattered clumps of coniferous trees. mild, rainy winters and hot, dry summers w/ periodic fires. located in middle latitudes, about 30 north and south of equator. found primarily in coastal regions.
desert	receive less than an average odf 25 cm of rain each year. mostly humid and hot, some can have cool winters. temperatures fall rapidly at night.
