As the earth warms, more permafrost melts releasing copious amounts of methane. This further increases the greenhouse effect and enhances global warming.

• Positive feedback loop

• Negative feedback loop

A population of beetles declines due to high predation rates by birds. As the population of beetles declines, the population of birds begins to decline as well. This allows the population of beetles to once again increase and find stability.

• Positive feedback loop

• Negative feedback loop
