Ch. 22.3 Energy in Ecosystems pp.424-429 Biome = large ecosystem May have smaller ecosystems within Defined by patterns of Temperature Weather Rainfall Soil types Plant communities Animal communities Latitude Ch. 22.3 Energy in Ecosystems pp.424-429 Terrestrial = land, earth, terra Aquatic = water, aqua

Ch. 22.3 Energy in Ecosystems pp.424-429 Patterns of: Latitude Biome makeup Ch. 22.3 Energy in Ecosystems pp.424-429

Ch. 22.3 Energy in Ecosystems pp.424-429 Patterns in biome weather due to sun, wind, and season patterns.

Ch. 22.3 Energy in Ecosystems pp.424-429 Tundra = cold and treeless Grasses, lichens, grazers N. Canada, cold desert Ch. 22.3 Energy in Ecosystems pp.424-429 60°-80° North Latitude Cold and dry Species Richness LOW

Ch. 22.3 Energy in Ecosystems pp.424-429 Taiga = cold, evergreen forest Cold in winter, damp in summer Ch. 22.3 Energy in Ecosystems pp.424-429 45°- 70° North Cold and wet Species Richness LOW TO MODERATE

Ch. 22.3 Energy in Ecosystems pp.424-429 Temperature Deciduous Forest = Broadleaf forest Deciduous= falling off NE U.S., wet year-round Ch. 22.3 Energy in Ecosystems pp.424-429 30°-50° North or South Warm in summer, cold in winter Species Richness MODERATE

Ch. 22.3 Energy in Ecosystems pp.424-429 Temperate Grassland = prairies with rainfall year- round but less than forest Ch. 22.3 Energy in Ecosystems pp.424-429 30°-50° N or S Hot & Cold and drier Species Richness MODERATE

Ch. 22.3 Energy in Ecosystems pp.424-429 Desert = hot & dry, few plants 15°- 30° N or S Ch. 22.3 Energy in Ecosystems pp.424-429 15°- 30° N or S Hot and dry all year Species Richness MODERATE Biomass is low

Ch. 22.3 Energy in Ecosystems pp.424-429 Savanna = tropical grasslands, similar to prairie; seasonal wet season and dry season Large herbivores Ch. 22.3 Energy in Ecosystems pp.424-429 10°- 30° N or S Hot and wet or hot and dry Species Richness LOW TO MODERATE Biomass is much higher than desert

Ch. 22.3 Energy in Ecosystems pp.424-429 Tropical rainforest = hot and wet Equatorial Vertically layered Ch. 22.3 Energy in Ecosystems pp.424-429 0°- 20° N or S Hot and wet all year Species Richness EXTREMELY HIGH Biomass is high
