Biomes

Explore the world's diverse biomes, including deserts, forests, grasslands, tundra, and aquatic regions. Learn about the unique characteristics of each biome, such as temperature, precipitation, soil quality, and biodiversity. Discover how biomes regulate the global climate and provide natural resources for human use.

Presentation Transcript

  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 Boreal • Tundra • Grasslands • Boreal Forests • Deciduous Forest • Coastal Forest • Mountain Coastal Deciduous Mountain 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
