Glossary Terms 1.1
Show Answers:

  1. Ecosystem
    All of the interacting parts of a biological community and it's environment.

    • Examples:
    • -Forest
    • -Ocean
    • -Desert
  2. Sustainable Ecosystem
    An ecosystem that can sustain itself for a long period of time.
  3. Biotic
    The living parts of an ecosystem.

    • Examples:
    • -Rabbit
    • -Trout
  4. Abiotic
    The non-living parts of an ecosystem.

    • Examples:
    • -Rocks
    • -Lakes
  5. Lithosphere
    The hard part of earth's surface.

    Example: Caves, Deserts
  6. Hydrosphere
    • All the water found on Earth, including lakes, oceans, and ground water.
    • Example: Oceans, lakes
  7. Atmosphere
    • The layer of gasses above Earth's Surface.
    • Example: Oxygen, nitrogen, carbon dioxide.
  8. Biosphere
    • The regions of Earth where living organisms
    • exist. Example: Forests, Swamp
  9. Nutrients
    A chemical that is essential to living things and is cycled through ecosystems.

    • Example:
    • Phosphorus
    • Nitrogen
  10. Eutrophication
    A process in which nutrient levels in aquatic ecosystems increase, leading to an increase, leading to an increase in the populations of primary producers.

    • Example:¬†
    • -Nitrogen
    • -Phosphorus
  11. Photosynthesis
    A process that changes solar energy into chemical energy.
  12. Trophic level
    A category of organisms that is defined by how the organisms gain their energy.

    Sunlight->Producers->Primary consumer-> Secondary consumer->Tertiary consumer.
  13. Biomass
    The total mass of living organisms in a 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 them.
  16. Biomagnification
    A process in 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.

    Glucose + oxygen = carbon dioxide + water.
  18. Fermentation
    A process that releases energy from organic molecules, especially carbohydrates, in the absence of oxygen. Some types of bacteria use this process.
  19. Greenhouse Gases
    Atmospheric gasses that prevent heat from leaving the atmosphere, thus increasing the temperature of the atmosphere.

    • Example:
    • Carbon dioxide
    • Methane
    • Water vapour
  20. Greenhouse Effect
    The warming of Earth as a result of greenhouse gasses, in which trap some of the energy that would otherwise leave earth.
  21. Acid Precipitation
    Rain, snow or fog that is unnaturally acidic (pH less that 5.6) due to gasses in the atmosphere that react with water to form acids.
