  1. Population:
    All the individuals of a species that occupy a particular geographic area at a certain time
  2. Exponential Growth:
    Accelerating growth that produces a J-shaped curve when the population is graphed against time
  3. Limiting Factors:
    A factor that limits the growth, distribution, or amount of a population in an ecosystem
  4. Carrying Capacity:
    The size of a population that can be supported indefinitely by the available resources and services of an ecosystem
  5. Ecological Niche:

  8. Mutualism:
    A symbiotic relationship between organims where both parties benefit from the relationship
  9. Parasite:

  10. Competition:
    When two or more organisms compete with each other for the same resource in the same area in the same timeframe
  11. Sustainable Use:
    Use that does not lead to a long-term depletion of a resource or affect the diversity of the ecosystem from which the resource came
  12. Doubling Time:
    The amount of time it takes a population to double in size
  13. Ecological Footprint:
    A measure of the impact of an individual or a population on the environment in terms of energy use, land use, and waste production
  14. Unsustainable:
    A pattern of activity that leads to a decline in the function of an ecosystem
  15. Sustainability:
    Use of Earth's resources, including land and water, at levels that can continue forever
  16. Ecosystem Services:
    The benefits experienced by organisms, including humans, that are provided by sustainable ecosystems
  17. Desertification:
    The change of non-desert land into desert land, which could result from climate change, unsustainable farming activities, or unsustainable water use
  18. Ecotourism:
    A form of tourism that is sensitive to the health of an ecosystme and involves recreational activities provided by sustainable ecosystems
