  13. Biomass
    The total mass of living organisms in a defined group or area

  15. Bioaccumulation
    A process in which materials, especially toxins, are ingested by an organism at a rate greater than they are eliminated.

  16. Biomagnification
    When concentration of a material/toxin accumulates in progressively higher concentrations toward the top of the food chain

  17. Cellular respiration
    A process that releases energy from organic molecules, especially carbohydrates, in the presence of oxygen

    Image Upload
  18. Fermentation
    A process that releases energy from organic molecules, especially carbohydrates, in the absence of oxygen

    Image Upload
  19. Greenhouse gases
    Atmospheric gases that prevent heat from leaving the atmosphere, thus increasing the temperature of the atmosphere

    Image Upload
  20. Greenhouse effect
    The warming of the Earth as a result of greenhouse gases, which trap some of the energy that would otherwise leave Earth

    Image Upload
  21. Acid precipitation
    Rain, snow, or fog that is unnaturally acidic due to gases in the atmosphere that react with water to from acids
