1. Biomes SNC1L Science

2. 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

6. Canada’s Biomes Tundra Grasslands Boreal Forests Deciduous Forest Coastal Forest Mountain Tundra Boreal Deciduous Mountain Coastal Grassland

7. 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
