Zombie Fires and Arctic Fire Patterns Quiz

Which of the following regions is NOT mentioned as having significant peatland coverage in the Northern Hemisphere?

• Australia

• Russia

• Canada

• Alaska

What is permafrost?

• A mixture of rock, soil, ice, and peat that remains frozen for at least two years in a row

• A type of wetland found only in tropical regions

• A layer of soil that never freezes

• A type of forest soil rich in carbon

Based on the information provided, what might be the environmental impact if permafrost in peatlands were to thaw significantly?

• Large amounts of stored carbon could be released into the atmosphere, contributing to climate change.

• There would be no impact on the environment.

• The soil would become more fertile for agriculture.

• The peatlands would turn into deserts.

How do living organisms return carbon to the atmosphere in the carbon cycle? (a)  

• respiration and photosynthesis

• decomposition and respiration

Answer explanation

Living organisms return carbon to the atmosphere primarily through decomposition and respiration. Decomposition breaks down organic matter, releasing carbon dioxide, while respiration by animals and plants also emits CO2.
