What is a biome? • Many ecosystems combined sharing the same climate and soil conditions. • Organisms are adapted structurally and behaviorally to that particular biome • Ex: Saguaro and anthodium • Organisms in biomes demonstrate tolerance. – What is that? Go to Section:

Compare/Contrast Table Section 4 -3 Ten Major Biomes Biome Precipitation Temperature Soil Diversity Trees Grasses Tropical Rain Forest high hot poor high dense sparse Tropical Dry Forest variable mild rich moderate medium Tropical Savanna variable mild clay moderate sparse dense Desert low variable poor moderate sparse Temperate Grassland moderate summer hot rich moderate absent dense Temperate woodland summer low, and Shrubland winter moderate summer hot poor low medium Temperate Forest moderate summer moderate, rich winter cold high dense sparse Northwestern Coniferous Forest high summer mild, winter cold rocky, acidic low dense sparse Boreal Forest moderate summer mild, winter cool poor, acidic moderate dense sparse Tundra low summer mild, winter cold poor low absent medium Go to Section:

Generally speaking…… • What adaptations do plants and animals have for the biomes they live in? • Example: What are plants like in temperate climate? . . Go to Section:

• Tropical Rainforest Go to Section:

• Temperate Rainforest Go to Section:

• Desert Go to Section:

• Taiga • Coniferous forest • Boreal forest Go to Section:

• Savannah • Dry grassland, poor soil, and sparse trees Go to Section:

Other land areas • Tundra – a world of long winters, and very short summers Go to Section:

Other land areas • Mountain ranges – Varies elevation – How does that influence climate? • Polar ice caps – Cool surrounding water – Cool air – What does that mean? Go to Section:
