  1. Ecosystem
    -All the interacting parts of a living community and that community's environment.
  2. Sustainable ecosystem
    - Ecosystem that can withstand pressure and give support to a variety of organisms
  3. Biotic
    - All the living or recently living parts of an ecosystem
  4. Aboitic
    -The non living parts of an ecosystem that organisms need to survive
  5. Lithosphere
    -Hard part of the Earth's surface (Includes rock and oil)
  6. Hydrosphere
    -Liquid part of the earth's surface (Includes salt water oceans, freshwater lakes, rivers)
  7. Atmosphere
    -Layer of gasses above Earth's surface (Including air)
  8. Biosphere
    -Living part of Earth's surface (Not separate from other abiotic spheres; includes life in soil, water, and air)
  9. Nutrients
    • -Chemicals needed by living organisms to survive.
    • -Cycled through Earth's spheres.
  10. Eutrophication
    • -The process of adding nitrogen or phosphorus to an ecosystem
    • - Adding these substances will push  the ecosystem beyond the normal nutrient cycle and beyond sustainability
  11. Photosynthesis
    • -The conversion of solar energy to chemical energy (To be used as food)
    • (In the presence of light) Carbon dioxide + water --------------> Glucose + Oxygen           (Chlorophyll is needed)
  12. Trophic Levels
    -Categories of organisms defined by how the organisms gain energy
  13. Biomass
    -The total mass of living organisms in a defined group or area
  14. Trophic Efficiency
    -A measure of the amount of energy or biomass transferred from one trophic level to the next higher trophic level
  15. Bioaccumulation
    -A process in which materials especially toxins, are ingested (absorbed) by an organism at a rate greater than they are eliminated
  16. Biomagnification
    -Is the increase in the concentration of a toxin as it moves from one trophic level to the next
  17. Cellular Respiration
    -The most common and efficient method for extracting the energy from glucose

    Glucose + Oxygen -------> Carbon dioxide + Water + Energy
  18. Fermentation
    -A process that releases energy from organic molecules
  19. Greenhouse Gases
    -Atmospheric gases  that prevent heat from leaving the atmosphere, thereby increasing the temperature in the atmosphere
  20. Greenhouse Effect
    -The warming of Earth as a result of greenhouse gasses
  21. Acid Percipitation
    -Rain, snow, or fog that is unnaturally acidic due to gases in the atmosphere which react with water to form acids
