2. Nutrient cycles

3. The nitrogen cycle

6. Inputs of nutrients : 1.Precipitation & dry deposition 2.Weathering of bedrock 3.[Artificial supplements]

7. Three possible stores : 1.Soil 2.Leaf litter 3.Biomass

8. Outputs of nutrients : 1.Runoff 2.Leaching 3.[Human removal]

9. Where are the nutrients stored in an ecosystem? the answer varies from one ecosystem to another dependent on : –temperature –precipitation –vegetation type

10. Gersmehl diagrams how do the inter-relationships between nutrient stores and flows differ between biomes? a big question! best answered with DIAGRAMS…

11. Temperate deciduous forest balance between stores moderate transfers between stores

12. Boreal forest (taiga) litter is main store (needles) little transfer between stores

13. Tropical rain forest biomass is main store rapid transfer between stores and environment
