Why don’t polar bears live in the desert?
Polar bears don’t live in the desert because they are adapted to very cold environments

Imagine yourself in a hot, dry , dusty place. Your see a cactus on your right, and a lizard on your left. Where are you?

Biome A large region characterized by a specific type of climate and certain types of plant and animal communities
Eight Major Biomes

Different biomes
Forest Biomes
•Found in mild temperature areas•Plenty of rain•Development depends on temperature and rainfall

Three types of forest biomes
•Temperate deciduous•Coniferous forest•Tropical rain forest

Temperature Deciduous Forest
• Average yearly rainfall 75 to 125 cm•Average temperature Summer: 28˚ C (84˚F) Winter: 6˚C (43˚F)•Variety of animals
•Animals survive on leaves, seeds, nuts, and insects.

Coniferous Forest
•Most tree are called conifers•Average yearly rainfall 35 to 75 cm (14 to 29.5 in.)•Average temperatures Summer: 14˚C (57˚F) Winter: -10˚C (14˚F)•Very little light reaches the ground, few plants grow beneath these trees

Tropical rain forest
•More biodiversity than other place on Earth•Average yearly rainfall up to 400 cm (157.5 in.)•Average temperaturesDaytime: 34˚C(93˚F)Nighttime: 20˚C (68˚F)•Over 100 different kinds of tree may grow•Most animals live the canopy•Very thin soil

Grassland •Found on every continent but not Antarctica.•Often flat or have gently rolling hills

Temperate Grassland
•Average yearly rainfall 25 to 75 cm (10 to 29.5 in.)•Average temperature Summer: 30˚C (86˚F)Winter: 0˚C(32˚F)•Few trees•Small seed eating animals•Large grass eaters such as bison

Savannas •Clumps of trees and seasonal rains•Found in parts of Africa•Average yearly rainfall 150 cm (59 in.) •Average temperatures Dry season: 34 ˚C(93˚F)Wet season: 16˚C(61˚F)•Home to large herbivores • Elephants•Giraffes• Zebras•Wildebeests

Deserts •Average yearly rainfall less than 25 cm (10 in.)•Average temperatures Summer: 38 ˚C(100˚F) Winter: 7˚C(45˚F)•Very dry and hot

Tundra •Average yearly rainfall 30 to 50 cm (12 to 20 in.)•Average temperature Summer: 12˚C (54˚F) Winter: -26 ˚C(-15˚F)•Very cold and little rainfall•Two types polar and alpine tundra

Polar Tundra •Found near the North and South Poles•Permafrost•Shallow rooted plants•Birds, wolves, caribou,
