Navigate - Peat and Zombie Fire Systems

With your class: What did we figure out about peat and why it burns so much?

• Peat burns so much because it is made of partially decayed plant material that is rich in carbon.

• Peat burns so much because it is mostly made of water.

• Peat burns so much because it is a type of metal.

• Peat burns so much because it is always wet.

There is so much peat trapped in the permafrost because:

• the cold temperatures prevent the peat from decomposing quickly.

• the peat is constantly being burned away.

• the peat is washed away by rain every year.

• the peat is eaten by animals in the permafrost.

There is so much energy and matter in the peat because:

• Peat forms from the accumulation of partially decayed plant material, which stores energy and matter.

• Peat is made entirely of minerals with no organic material.

• Peat is created by volcanic activity, which adds energy and matter.

• Peat is formed from pure water, which contains a lot of energy and matter.

Investigating how decomposition is involved in the flow of matter and energy in the zombie fire system can be done by:

• Observing how decomposers break down organic material and release nutrients.

• Ignoring the role of decomposers in the system.

• Focusing only on the movement of living organisms.

• Studying only the temperature changes in the soil.

There is so much peat in the permafrost because:

• cold temperatures slow down the decomposition of plant material

• peat forms quickly in permafrost due to high temperatures

• permafrost is mostly made of sand and rocks

• peat is created by animal activity in the permafrost

Matter like plants breaks down through a process called:

• Decomposition

• Photosynthesis

• Evaporation

• Condensation

What conditions in the zombie fire system could affect decomposition and keep the matter and energy in the system?

• Low oxygen levels and cold temperatures

• High humidity and sunlight

• Abundant rainfall and warm temperatures

• Strong winds and frequent storms

If yeast is a decomposer, how does it interact with matter and energy?

• Yeast breaks down dead organic matter and releases energy.

• Yeast produces its own food using sunlight.

• Yeast consumes only living organisms for energy.

• Yeast stores energy without breaking down matter.
