An Introduction to Biomes An Introduction to Biomes Presentation Transcript

  • Definition Biomes are similar kinds of ecosystems found around the world; biomes are characterized by their physical conditions (abiotic factors e.g. rainfall and temperature throughout the year) and the communities of organisms that interact in these conditions.
  • Where are they located? Play the Game http://www.purposegames.com/game/1445 Extension: What is the difference between a biome, an ecosystem and a habitat
  • Where are they located?
  • What effects their location? Latitude • Altitude Climatic Conditions • Solar radiation • Effect of seasons • Atmospheric circulation • Evaporation
  • Latitude & Altitude
  • Solar Radiation
  • Effects of seasons
  • Atmospheric Circulation
  • Limiting factors – Temperature & Precipitation
  • Spot Quiz Wettest place on Earth Hottest place on Earth Driest Place on Earth Coldest place on Earth
  • Effects of Evaporation Ratio between Precipitation (P) & Evaporation (E) • P>E → Increase leaching and loss of nutrients • P<E → Increase in salinity • P=E → Soil rich and fertile
  • Tundra Temperate Forest Boreal Forest Subtropical Desert Tropical Rain Forest Know your Biome
  • Key Learning • What is a Biome? • Types of Biomes & their location? • Factors effecting their distribution? – Climatic e.g. solar radiation, temperature, rainfall, evaporation – Terrain Future Learning – Key characteristics of individual biomes, adaptations, types of productivity (Net, Gross, Primary, Secondary)
