Question

Which sequence of events best explains the interaction between the components of the Arctic ecosystem feedback loop

Answer 1

The sequential events in the Arctic ecosystem feedback loop are: Global temperature increases → permafrost thickness decreases → methane increases → global temperature increases. It is harmful to the Earth.

The Arctic ecosystem is a feedback loop because the warmer the temperatures, the less sea ice (permafrost) is observed.

The Arctic ecosystem feedback loop is a dangerous phenomenon because it accelerates global warming.

Permafrost refers to ice ground that remains completely frozen (0°C) for at least two (2) or more years straight.
