Tundra |
-Only occur in extreme northern latitudes -Extreme harsh winters and short summers -Very little precipitation;4-10"/year -Soil is very young>covered by glaciers -Always frozen:permafrost |
|
|
Boreal forest |
-only found in northern latitudes;just below tundra -precipitation; 20"/year -11%of land mass on earth -deciduous trees;shed leaves in fall -caribau,moose, bears,wolves -humans use most of this for wood |
|
|
Temperate forests |
-lots of rain/dense fog -50"/year -cold winters &warm summers -old growth forest -a lot of moss & lichens>fungus -smaller mammals (vs. Caribau/moose) |
|
|
Temperate deciduous forests |
-cold winters;hot summers -precipitation; 30-60"/year -smaller animals; coyotes, small cats -syrups/teas/berries |
|
|
Grasslands |
Cold winters/hot summers -precipitation; 10-30"/year -almost no trees -good for agriculture; lost 90% of all grasslands |

|
|
Tropical rainforests |
-warm all year long -precipitation; all the time (80-100"/year) -tons of plants:primary production -high biodiversity |
|
|
Elevation plays a ___________ in the environments. |
Role |
|
|
3 major ecosystems |
-SW (ocean):lots of nutrients, lack minerals -brackish environments: (estuaries, wet lands) both FW/SW influence ( lots of both) -FW:lots of minerals, lack nutrients |
