  2. Exponential growth

  3. Limiting factors
    A factor that limits the growth, distribution or amount of a population in an ecosystem.
  4. Carrying capacity
    The size of the population that  can be supported indefinitely by the available resources and services of an ecosystem.
  5. Ecological niche

  6. Predator

  10. Competition
    When two or more organisms compete for the same resource in the same location at the same time.
  11. Sustainable use
    Use that does not lead to long-term depletion of a resource or affects the diversity of the ecosystem from which the resource was obtained.
  12. Doubling time
    The time that is required for 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 consumption, land use, and waste production is called an ecological footprint.
  14. Unsustainable
    When a pattern of activity leads to a decline in the function of an ecosystem.
  15. Sustainability
    Use of Earth's resources , including land and water, at levels can that can continue forever.
  16. Ecosystem services
    The benefits experienced by organisms, including humans that are provided by sustainable ecosystems.
  17. Desertification
    desertification is a change in non desert land into desert; desertification may result from climate change and unsustainable farming or water use.
  18. Ecotourism
    A form of tourism that is sensitive to the health of an ecosystem and involves recreational activities provided by sustainable ecosystems
