trapped in the frozen ice

trapped in the peat

trapped in the soil

trapped in the rock

2

The hypothesis of this lab was decomposition happens faster in warmer conditions. Was the hypothesis supported?

yes

no

2

Why do zombie fires tend to occur more often when the Arctic experiences warmer than normal summers?

increased lighting strikes

thawing of permafrost

human interference

enhanced fire prevention measures

2

What significant environmental concern is associated with zombie fires?

rapid soil cooling

mass migration of animals

release of carbon dioxide into the atmosphere

decline in global temperatures

What did the banana peel help us remember about what happens to plants when they die?

A. When plants die, they magically disappear

B. When plants die, they decompose and nutrients are recycled

C. When plants die, they are converted into oxygen gas

What evidence did we collect from BANANA and YEAST systems that can help us understand how decomposition works in the peat/permafrost system

A. Decomposition occurs faster in colder temperatures

B. Decomposition occurs faster in warmer temperatures

C. Temperature does not affect the rate of decomposition

In warmer conditions, the yeast broke down more sugar and produced more

A. oxygen gas

B. carbon dioxide gas

Yeast is breaking down sugar by performing what process?

A. photosynthesis

B. mitosis

C. cellular respiration

D. DNA replication

How does this experiment relate to the peat/permafrost system?

A. The temperature in the Arctic is getting warmer so more peat is decomposing which is releasing more CO2 into the air.

B. The temperature in the Arctic is getting colder so more peat is decomposing which is releasing more CO2 into the air

C. The temperature in the Arctic does not change the rate at which peat is decomposing
