    • -some species rely on multiple ecosystems
    • -Eg: Atlantic ocean, Boreal forests
  2. Sustainable Ecosystem
    • -An ecosystem that is capable of withstanding pressure and giving support to a variety of organisms
    • -all organisms require sustainable ecosystems to survive
  3. Biotic
    • -Any living part of an ecosystem
    • -includes recently living organisms
    • -makes up the biosphere
    • -Eg: Animals, fungi, microscoptic organisms
  4. Abiotic
    • -the non-living parts of an ecosystem
    • -Eg:rocks,soil,air
  5. Lithosphere
    • -Hard part of earths surface(ground)
    • -Eg: rocks, soil
  6. Hydrosphere
    • -Liquid part of earths surface(water)
    • -Eg: Lakes, oceans
  7. Atmosphere
    • -Layer of gases above earths surface(air)

    • -happens when excess amounts of phosphorus or other nutrients enter a body of water
    • -Eg: fertilizer run-off
  11. Photosynthesis
    • 6CO2+6H2O-->C6H12O6+6O2
    • carbon dioxide+water=glucose+oxygen
    • -can be carried out by plants, algae, and some bacteria
    • -chlorophyll and sunlight are needed
    • -carbon, hydrogen and oxygen bond to make sugar(glucose)
