    • 1. The Carbon Cycle briefly: <ul><li>Has stores of carbon which hold the carbon </li></ul><ul><ul><li>Atmosphere </li></ul></ul><ul><ul><li>Soil and lithosphere (fossil fuels) </li></ul></ul><ul><ul><li>Vegetation </li></ul></ul><ul><ul><li>Oceans </li></ul></ul><ul><li>Carbon is TRANSFERRED between stores </li></ul><ul><ul><li>By respiration and photosynthesis </li></ul></ul><ul><ul><li>Plants are eaten and die </li></ul></ul><ul><ul><li>Decomposers </li></ul></ul><ul><ul><li>Burning of fossil fuels </li></ul></ul>
    • 2. Nutrient cycling Key terms: Nutrient cycle Biomass Soil Litter May 29, 2009
    • 3. Recycling of nutrients <ul><li>Ecosystems cycle nutrientd as well as transferring food energy </li></ul><ul><li>Two types: </li></ul><ul><ul><li>Micronutrients e.g. sulphur, magnesium </li></ul></ul><ul><ul><li>Macronutrients e.g. Oxygen, carbon, hydrogen and nitrogen </li></ul></ul>
    • 4. Sources of nutrients… Atmosphere Rocks Dead organic matter
    • 5. RECYCLING OF NUTRIENTS LITTER Surface layer of vegetation BIOMASS Weight of living material SOIL Additional nutrients added by weathering of parent rock Trees and organisms die Plants take up nutrients Some nutrients lost due to leaching Decomposition of plants and leaves releases nutrients The Nutrient Cycle
    • 6. The rainforest/ selvas nutrient ecosystem Biomass-trees and plants Litter Soil Gain from precipitation Gain from weathering Loss from leaching A carboniferous tropical rainforest is an evergreen forest – leaves grow all year Runoff
    • 7. Steppe and prairie grasslands B L S Gain from precipitation Gain from weathering Loss from leaching Runoff
    • 8. Northern coniferous forest (Taiga) B L S Gain from precipitation Gain from weathering Loss from leaching Runoff
    • 9.  
    • 10. Factors influencing the stores and transfers of nutrients
    • 11. Homework <ul><li>Complete a written comparison of the selvas (tropical rainforest) nutrient cycle, the prairie nutrient cycle and the taiga nutrient cycle. </li></ul>
