What are Biomes?

• Large regions of the world with similar
• CLIMATE, PLANTS ANIMALS
• Areas with different biodiversity
• They help regulate global climate
• Humans live in them use them for natural
  resources, food sometimes, a little too much!

3
Major World Biomes

• Deserts
• Grasslands
• Forests Deciduous Coniferous Mixed Tropical
• Tundra
• Also Aquatic Marine!

4
Desert Biome

• High Temperatures
• Low Precipitation
• Short growth season
• Poor soil quality
• Slow decomposition
• Succulent plants, tap roots, cacti
• Reptiles, birds mammals with short fur, long
  extremities.

5
Tropical Forest Biome

• High Temperatures
• High Precipitation
• No seasonal change
• Poor soil quality
• Fast decomposition
• Very tall trees create a canopy lower in
  understory
• Colourful birds amphibians well-camoflauged
  mammals

Tundra Biome

• Low Temperatures
• Low precipitation
• V.Short growth season
• Poor soil quality - Permafrost
• Slow decomposition
• No trees mosses, lichens, small plants
• Seasonal colour change in animals migrators.

8
Boreal Forest Biome

• Low Moderate Temp.
• Low precipitation
• Short growth season
• Acidic soil
• Faster decomposition
• Conifers, lichens
• Hibernating mammals
• Animals that can consume conifer needles seeds.

9
Deciduous Temperate Forest

• Moderate Temp.
• Moderate precipitation
• 6 mon. growth season
• Rich soil
• Fast decomposition
• Deciduous trees
• Migratory birds
• Wide diversity of mammals
• Most biodiverse biome!

10
Grasslands Biome

• Mod. - High Temp.
• Moderate precipitation
• 5 mon. growth season
• Fairly fertile soil
• Fast decomposition
• Tall grasses, shrubs
• Drought tolerance
• Burrowing animals
• Reptiles, diverse mammals birds

11
Ecotones

• Transitional Areas where two biomes meet
  cross over
• Taiga T/BF ecotone
• Scrub G/BF ecotone
• Mixed Forest ecotone of DF/BF or DF/G
