Clues

  • A global ecosystem. (5)
  • a self-regulating biological community in which the living (biotic) interact with the non-living (abiotic). (9)
  • An area of high biodiversity (7)
  • The amount of unique & rare species presnt in a particular location. (8)
  • the number of ecosystems within a given area. Partly controlled by physical conditions such as climate, geology, relief & soils. The ability of humans to change & eliminate ecosystems is a threat to ecosystem diversity. (9, 9)
  • the range of genes found within a particular species. Often determines the degree of resistance to pests & diseases. (7, 9)
  • the rate at which energy is converted into organic matter. Can be measured by the amount of biomass produced each year. May be measured in terms of GPP (gross primary productivity) or NPP (net primary productivity) (7, 12)
  • the variability among living organisms from all sources- terrestial, marine & aquatic ecosystems & the ecological complexes of which they are part; this included diversity within species & ecosytems (12)
  • the variety of plant & animal species present in an ecosystem. Diversity is needed to enable the ecosystem to carry out its functions such as carbon cycling (7, 9)
