Flashcards of chapter 1 for the ecology unit
Show Answers:

  1. Ecosystem
    A biological community of organisms and their environment.

    Example; lakes, deserts, oceans, tropical rain forest's
  2. Sustainable Ecosystem
    • An ecosystem that can stand drastic pressure
    • (earthquakes, pollution, tornado's etc)

    AndĀ can support lots of organisms

    Example; our ecosystem supports humans as well as birds, insects, amphibians, and reptiles
  3. Biotic
    All the living, or recently living attributes to an ecosystem

    Example; plants, animals, fungi, micro-organisms
  4. Abiotic
    All the non living attributes to an ecosystem

    Example; chemical nutrients, sun, soil, water, oxygen, food
  5. Lithosphere
    The rigid part of the Earth's surface
  6. Hydrosphere
    Any source of water found on the earth's surface

    Example; lakes, waterfalls, seas, ponds
  7. Atmosphere
    All the gases above Earth's surface
  8. Biosphere
    Any place on the Earth's surface occupied for living organisms

    Example; cities, towns, resorts, countries, forests
  9. Nutrients
    Elements that are essential to the growth of living organismsĀ 

    Example; calcium, potassium, fiber, magnesium
  10. Eutrophication
    When aquatic ecosystems have an excessive increase of nutrients, usually from land run off
  11. Photosynthesis
    Solar energy being turned into chemical energy is the process of photosynthesis
  12. Trophic Level
    Organisms are categorized by the way they gain their energy by the trophic level
  13. Biomass
    The total mass of a group of specific organisms in a specific area or group
  14. Trophic Efficency
    The measure of biomass or energy as it moves up or down the tropic scale.
  15. Bioaccumulation
    When a toxin or material ingested by one organism isn't eliminated as fast as it's ingested
  16. Biomagnification
    The transfer materials and toxins from one organism to another as it moves up the trophic scale
  17. Cellular Respiration
    The process of which the glucose from photosynthesis is broken down to use as energy, in the presence of oxygen
  18. Fermentation
    Like Cellular Respiration, fermentation is also a process in which energy is released but without the presence of oxygen
  19. Greenhouse Gases
    Gas in the atmosphere that changes the temperature of the Earth.
  20. Greenhouse Effect
    The insulating capacity of greenhouse gases
  21. Acid Precipitation
    Any form of precipitation that is acidic because of the reaction from gases and water.
