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?

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

Taiga Coniferous forest Boreal forest
10
Savannah Dry grassland, poor soil, and sparse trees
11
Tundra – a world of long winters, and very short summers
Other land areas Tundra – a world of long winters, and very short summers
12
Other land areas Mountain ranges Varies elevation
How does that influence climate? Polar ice caps Cool surrounding water Cool air What does that mean?
