  1. Ecosystem
    • -A group or biological community with interacting parts (organisms) and their physical environment (biotic-abiotic)
    • -E.g. forest, pond, arctic, sea, tundra, rain forest
  2. Sustainable Ecosystem
    • -An ecosystem that can withstand pressure and flourish for many generations without human aid, while also giving support to a variety of organisms. 
    • -E.g. A non polluted forest with a thriving food chain
  3. Biotic
    • -The living or recently living parts of an ecosystem, which consists of producers (plants) and consumers (animals,microorganisms, and fungi)
    • -E.g. plants,animals,fungi,bacteria and protists
  4. Abiotic
    • -The non-living parts of the ecosystem that organisms need to survive. 
    • -E.g. water, air (oxygen), light, chemical nutrients, soil
  5. Lithosphere
    • -The rigid, hard part of the Earth's surface; includes rock and soil
  6. Hydrosphere
    • -The liquid part of the Earth's surface, all of the water on the surface
    • -This includes salt water oceans, freshwater lakes, rivers and lakes

  7. Atmosphere
    • -The layer of gases above the Earth's surface
    • -This includes air, (oxygen, nitrogen, and carbon dioxide)
  8. Biosphere
    • -The regions of the surface, living part of Earth's surface with air, water and occupied by living organisms 
    • -E.g. Any area which consists of these attributes
  9. Nutrients
    • -A substance which lets life nourish and is essential for growth and maintenance of life
    • -E.g. Protein, vitamins and minerals
  10. Eutrophication
    • -The process of adding nitrogen or phosphorus to an ecosystem that pushes it beyond the normal nutrient cycle which it can no longer sustain
    • -E.g too much fertilizer causes the algae boom process
  11. Photosynthesis
    • -The process of plants and other organisms converting solar energy to chemical energy, to be used as "food" and also create oxygen.
    • -Word Equation
    • Carbon Dioxide + Water (in the presence of light)/(chlorophyll is needed) glucose + oxygen
  12. Trophic Level
    • -Categories of organisms defined by how the organisms gain energy, these organisms share the same function in the food chain
    • -E.g Primary producers>primary consumers>secondary consumers>tertiary consumers
  13. Biomass
    • -The total mass of living organisms in a given 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 by an organism at a rate greater than they are eliminated.
    • -E.g DDT, PCB's)
    • -Bioaccumulation of toxins from human-made pollution can be destructive to a species
  16. Biomagnification
    • -The increase of the concentration of a toxin as it moves from one trophic level to the next
    • -E.g. a large fish would have a larger concentration of toxins because it eats more smaller fish which already ingested toxins
  17. Cellular Respiration
    • -A process that releases energy from organic molecules, especially carbohydrates in the presence of oxygen
    • -Converts biochemical energy from nutrients into adenosine triphosphate
  18. Fermentation
    -A process that releases energy from organic molecules, especially carbohydrates, in the absence of oxygen which typically involve effervescence and the giving off of heat
  19. Greenhouse Gases
    • -A gas that is responsible and contributes to the greenhouse effect by absorbing infrared radiation
    • -E.g. Carbon Dioxide, methane and nitrous oxide
  20. Greenhouse Effect
    • -The trapping of the sun's warmth in the planet's lower atmosphere, which is caused by greenhouse gases that let the sunlight to go through but absorb the heat as well. 
  21. Acid precipitation
    -Acid rain is a form of precipitation that is more acidic than clean rain (pH 5.6) caused by fossil fuels burning which causes gases that combine with water into sulfuric and nitric acid.
