  1. Ecosystem
    An ecosystem is all the interacting parts of a biological community within an environment.
  2. Sustainable Ecosystem
    A sustainable ecosystem is an ecosystem that can withstand pressure and give support to a variety of organisms.
  3. Biotic
    Biotic means the living parts of an ecosystem.
  4. Abiotic
    Abiotic is the opposite of biotic and is the non-living parts of an ecosystem.
  5. lithosphere
    The lithosphere is the hard part of earth.
  6. Hydrosphere
    The hydrosphere is all the water on earth above ground and below ground.
  7. Atmosphere
    The atmosphere is the layer of gases above earth's surface.
  8. Biosphere
    The biosphere is the areas of earth where there are existing live organisms.
  9. Nutrients
    Nutrients are an essential chemical for all living organisms and are cycled through different ecosystems.
  10. Eutrophication
    Eutrophication is a process where there is a rise of nutrient levels in aquatic ecosystems which leads to and increase of primary producers(e.g. algae).
  11. Photosynthesis
    Photosynthesis is process where a plant takes in solar energy from the sun and changes it in to food. The outcome of this is the creation of glucose and the release of oxygen.
  12. Trophic Level
    Trophic level is a category based on how different organisms gain their energy.
  13. Biomass
    Biomass is the total mass of organisms in a specific group or area.
  14. Trophic Efficiency
    Trophic efficiency is the measure of energy or biomass transferred from one trophic level to the next highest level.
  15. Bioaccumulation
    Bioaccumulation is a process where materials, especially toxins are indigested by an organism at a faster rate than the material/toxin can be eliminated.
  16. Biomagnification
    Biomagnificaton is an increase in the concentration of the toxin as it moves from one trophic level to the next.
  17. Cellular Respiration
    Cellular respiration is where organic molecules release energy especially carbohydrates in the presence of oxygen.
  18. Fermentation
    Fermentation is like cellular respiration except organic molecule release energy especially carbohydrates in the absence of oxygen.
  19. Greenhouse Gases
    Greenhouse gases are atmospheric gases that prevent heat from the sun from leaving earth's atmosphere which increases the temperature of the atmosphere.
  20. Greenhouse Effect
    The greenhouse effect is the warming of the earth as a result of greenhouse gases that trap some of the heat that would usually leave.
  21. Acid Precipitation
    Acid precipitation is where water reacts with gases in the atmosphere such as nitric and sulfur acid thus creating acid rain, snow and fog.
