Section Outline Section 4-3 4–3 Biomes A. Biomes and Climate B. The Major Biomes C. Other Land Areas 1. Mountain Ranges 2. Polar Ice Caps

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?

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

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

Tropical Rainforest

Temperate Rainforest

Desert

Taiga Coniferous forest Boreal forest

Savannah Dry grassland, poor soil, and sparse trees

Tundra – a world of long winters, and very short summers Other land areas Tundra – a world of long winters, and very short summers

Other land areas Mountain ranges Varies elevation How does that influence climate? Polar ice caps Cool surrounding water Cool air What does that mean?
