  1. Ecosystem:
    • All the interacting parts of a biological community and its environment.
  2. Sustainable Ecosystem:
    A ecosystem that's able to withstand pressure and give support to other organisms.
  3. Biotic:
    The living parts of an ecosystem.
  4. Abiotic:
    The non-living parts of an ecosystem
  5. Lithosphere:
    The hard part of Earth's surface.
  6. Hydrosphere:
    • All the water found on Earth.
    • E.g. Lakes, Oceans, Rivers and Ground Water
  7. Atmosphere:
    The layer of gasses above Earth's surface.
  8. Biosphere:
    The regions of the Earth where living organisms exist.
  9. Nutrients:
    A chemical that's essential for living things to survive and is cycled through the ecosystem.
  10. Eutrophication:
    A process in which nutrient levels in aquatic ecosystems increase, leading to a increase in the primary producer population.
  11. Photosynthesis:
    A process that changes solar energy into chemical energy.
  12. Trophic Level:
    A category of organisms that is defined by how each organism gains energy.
  13. Biomass:
    The total mass of living organisms in a specific group or area.
  14. Trophic Efficiency:
    A measure of the amount of energy or biomass transferred from a trophic level to another one.
  15. Bioaccumulation:
    A process in which an organism ingests materials faster than they can eliminate them.
  16. Biomagnification:
    A process in which the concentration of ingested toxins increase  as it moves from one trophic level to the next.
  17. Cellular Respiration:
    A process that releases energy from molecules in the presence of oxygen.
  18. Fermentation:
    A process that releases energy from molecules in the absence of molecules.
  19. Greenhouse Gases:
    An atmospheric gas that prevents heat from leaving the atmosphere, which then increases the temperature.
  20. Greenhouse Effect:
    • The warming of Earth as a result of greenhouse gasses, which trap some of the energy that would leave Earth.
  21. Acid Precipitation:
    • Rain, Snow or fog that's unnaturally acidic.
