Systems thinking: inputs, outputs, and feedback loops — Homework
For each feedback question, state whether it is positive (amplifying) or negative (stabilizing) and explain why in one sentence.
- 1.A house's air conditioner shuts off once the room reaches the temperature on the thermostat. Classify this feedback.
- 2.A wildfire dries out nearby vegetation with its heat, making that vegetation more likely to catch fire too, spreading the blaze further. Classify this feedback.
- 3.Melting permafrost releases stored methane, which traps more heat and causes more permafrost to melt. Classify this feedback.
- 4.In a predator-prey system, prey numbers fall when predators are abundant, which then causes predator numbers to fall from lack of food, which lets prey recover. Classify this feedback.
- 5.Diagram, in words, one input-output system from your own home (water, energy, or food), naming at least one stock and one flow.
