  • The biosphere is the living layer of the earth. All plants and animals are found here.
  • The biosphere is divided into large regions called biomes. A biome is a large scale ecosystem. Each has its own climate, plant species and animal species
  • Importance of biosphere
    Services-Mangrove forests provide defences against coastal flooding, regulation of carbon dioxide and oxygen, water storage in glaciers prevents floods
  • Importance of biosphere
    Indigenous goods-rainforests are used sustainably by hunter gatherers who live in small, circular houses
  • Importance of biosphere
    Goods exploitation-when biomass is burnt, it releases carbon stores into the atmosphere, deforestation also takes away large nutrient stores which impacts the soil. Biomes are cleared for mining metal ores (copper/iron) and for timber. Decline in wetlands and animals because of increased demand in resources
  • Increase in water consumption
    Lake depletion from water usage
  • High demand for vehicles
    Pollution damages biomes
  • higher meat intake

    More animals from biomes removed
  • What determines the distribution and characteristics of biomes?
    • Sunshine
    • Tilt of the earth and length of the day
    • temperature
    • Human activity
    • Precipitation
    • Geology and soils
    • Wind and hurricanes
