Peat/Permafrost System: Components, Processes,
and Climate Impact Questions and Correct Answers |
Latest Update
What components make up the peat/permafrost system?
Ans: Living components like mosses, grasses, and decomposers
(bacteria and fungi), and non-living components like water, sediment, and
frozen soil (permafrost).
What is peat?
Assignment Expert
Ans: A dense layer of partially decomposed organic matter that has
built up over thousands of years.

How does matter enter the peat/permafrost system?
Ans: Matter moves from dead vegetation when plants die and sink into
wetlands, where it decomposes slowly due to water and cold
2026
temperatures.

What role does energy play in the peat/permafrost system?
Ans: Energy starts as light from the sun, which plants store in sugar
molecules, and flows through the system, remaining 'locked' in peat as
long as the ground is frozen.
What is the process of cellular respiration in the context of the
peat/permafrost system?
Ans: Cellular respiration 'unlocks' the peat by using oxygen to break
down sugar, transforming it into carbon dioxide gas and water, releasing
heat energy.
How do freezing temperatures affect cellular respiration in the
permafrost system?
