All 14 questions and answers

  1. Feedback that inhibits the original process, counteracting change and stabilizing the system?

    Answer: Negative feedback loop

  2. Feedback that amplifies a disturbance, destabilizing the system away from equilibrium?

    Answer: Positive feedback loop

  3. The minimum amount of change within a system that will destabilize it, causing it to reach a new equilibrium?

    Answer: Tipping point

  4. Large, persistent reorganization of an ecosystem's structure and function, e.g. coral reef to algae-dominated reef, after a tipping point is crossed?

    Answer: Regime shift

  5. Condition of an open system in which inputs and outputs balance over the long term, with only small short-term fluctuations?

    Answer: Steady-state equilibrium

  6. A simplified representation of reality used to understand and predict system behaviour?

    Answer: Model

  7. Properties that arise from component interactions but absent in the components individually?

    Answer: Emergent properties

  8. A system's capacity to resist and recover from disturbance without crossing a tipping point?

    Answer: Resilience

  9. Lovelock's model of Earth as one integrated system regulated by life through feedback mechanisms?

    Answer: Gaia hypothesis

  10. The extent to which practices allow long-term viability of a system for future generations?

    Answer: Sustainability

  11. Meeting present needs without compromising future generations' ability to meet their own (Brundtland, 1987)?

    Answer: Sustainable development

  12. Sustainability pillar focused on managing natural resources so they can be replaced and ecosystems can recover?

    Answer: Environmental sustainability

  13. Sustainability pillar focused on health, education, equity and community structures?

    Answer: Social sustainability

Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options are other answers from the same set.
