Tropical Rain Forest• Home to more species than all biomes
combined!
• Soil is poor b/c organic matter is recycled so quickly
• High temperatures and precipitation
Tropical Grassland/Savanna• Grassland spotted with trees and shrubs
• Fires by lightening and animals prevent land to turning into forest
• Waxy leaves to prevent water loss
• Has a dry season and most animals migrate/ burrow (oct)
• Has a rainy season (march)
Desert• Less than 25 cm of precipitation annually
• Extreme temperatures between hot & cold
• Rich soil minerals but poor organic matter
• Cacti store water, low surface area to prevent water loss, special photosynthesis
• Animals get water from food, nocturnal, regulate body temp with blood vessels close to surface.
Temperate Forest• Conifers – seed cones, waxy surface to
prevent water loss, cold winters.• Deciduous – shed leaves in autumn• Fertile soils rich in humus (organic matter)• Year round precipitation• Animals cope by
hibernation/migration/camouflaged
Taiga/Boreal Forest• Winters long and are bitterly cold
• Mild short summers , Ground thaws
• Northern Hemisphere
• Acidic poor soil
• Conifers
• Animals extra insulations, migrate
Tundra• Permafrost – permanently frozen subsoil.
Ground only thaws few centimeters
• Short cool summer
• Plants short b/c of permafrost, mosses
• Cold, windy, short growing season, poor soil
• Animals migrate or have adapted to live in cold climate.
