  3. Biotic:
    the living parts of an ecosystem
  4. Abiotic:
    the non-living parts of an ecosystem
  5. Lithosphere:
    Any hard part of the Earth's surface
  6. Hydrosphere:
    An water on the Earth, like rivers, oceans and lakes
  7. Atmosphere:
    The layer of gases above the Earth's surface
  8. Biosphere:
    The regions of Earth where living organisms exist
  9. Nutrients:
    An essential chemical to all living things that is cycled through the ecosystem
  10. Eutrophication:
    A process where the nutrients in an aquatic ecosystem increase, giving rise to a higher population of primary producers
  11. Photosynthesis:
    A chemical process in which plants convert sun energy and CO2 into oxygen and glucose
  12. Trophic level:
    a category of organisms that is defined by in which way the organisms get their energy
  13. Biomass:
    the total mass of living organisms in the 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 an organism ingests materials, especially toxins, faster than it eliminates the
  16. Biomaginfication:
    a process n which the concentration of ingested toxins increases as it moves from one trophic level to the next
  17. Cellular Respiration:
    a process that releases energy from organic molecules, especially carbohydrates in the presence of oxygen
  18. Fermentation:
    a process that releases energy from organic molecules, especially carbohydrates, in the absence of oxygen
  19. Greenhouse gases:
    an atmospheric gas that stops heat from leaving the atmosphere, then increasing the atmospheric temperature
  20. Greenhouse effect:
    the warming of Earth because of a greenhouse gas build-up, trapping heat that would otherwise leave Earth
  21. Acid precipitation:
    Rain, snow. or fog that is unnaturally acidic (pH below 5.6) caused by gases in the atmosphere that react with water to create acids
