2005-2006
Tropical rainforest
distribution: equatorialprecipitation: very wettemperature: always warmcharacteristics: many plants & animals, thin soil
2005-2006
Savanna
distribution: equatorialprecipitation: seasonal, dry season/wet seasontemperature: always warmcharacteristics: fire-adapted, drought tolerant plants; herbivores; fertile soil
2005-2006
Desert
distribution: 30°N & S latitude bandprecipitation: almosttemperature: variable daily & seasonally, hot & coldcharacteristics: sparse vegetation & animals, cacti, succulents, drought tolerant, reptiles, insects, rodents, birds
2005-2006
Temperate Grassland
distribution: mid-latitudes, mid-continentsprecipitation: seasonal, dry season/wet seasontemperature: cold winters/hot summerscharacteristics: prairie grasses, fire-adapted, drought tolerant plants; many herbivores; deep, fertile soil
2005-2006
Temperate Deciduous Forest
distribution: mid-latitude, northern hemisphereprecipitation: adequate, summer rains, winter snowtemperature: moderate warm summer/cool wintercharacteristics: many mammals, insects, birds, etc.; deciduous trees; fertile soils
2005-2006
Coniferous Forest (Taiga)
distribution: high-latitude, northern hemisphereprecipitation: adequate to dry (temperate rain forest on coast)temperature: cool year roundcharacteristics: conifers; diverse mammals, birds, insects, etc.
2005-2006
Arctic Tundra
distribution: arctic, high-latitude, northern hemisphereprecipitation: dry temperature: cold year roundcharacteristics: permafrost, lichens & mosses, migrating animals & resident herbivores
2005-2006
Alpine Tundra
distribution: high elevation at all latitudesprecipitation: dry temperature: cold year roundcharacteristics: permafrost, lichens, mosses, grasses; migrating animals & resident herbivores
