| tropical | warm year round |
| temprate | seasonal changes of weather |
| tropical rain forest | near equator, 100+ in. rain, most biodiversity, poor soil, canopy |
| taiga | northern Canada & Alaska, coniferous trees, short growing season, |
| tropical savannas | grasslands, near equator, less than 100 in. rain, largest number of grazing animals |
| temperate grasslands | plains of N. America, most fertile soil, seasonal climate |
| desert | less than 10 in. rain, rain shadows of mountains, soil high in minerals |
| tundra | north of Arctic circle, permafrost, insects/birds breed, no trees |
| tundra | migratory animals, very short growing season |
| temperate grasslands | plants have thick roots, grazers grow thick coats |
| desert | plants have waxy covering, water bulbs, dormant seeds |
| tropical savanas | animals migrate to areas of higher rainfall |
| littoral zone | shallow areas of laks/ponds, abundant life |
| benthic zone | deep dark waters, dead organic matter, bacteria |
| eutrophication | build up of plant life in ponds, |
| wetlands | marshes/swamps absorbs carbon dioxide |
| estuaries | areas where salt & fresh water mix, richest amount of nutrients |
| coral reefs | made of limestone, most diverse ecosystem on earth |
| temperate rain forest | cool & humid climate, largest trees on earth, Northwest US |
| temperate deciduous forests | broad leaf forests, 4-6 month growing season, rich soil, seasonal climate |
