Arctic's Past
How long did it take to form peat?
11,000 years
What is the main fuel source of zombie fires?
Peat
Name 2 things that do cellular respiration
Humans
Trees
Elephants
Mushrooms
What are the outputs of photosynthesis? (What is created by the end)
Sugar, Oxygen
The matter in peat flows to...
(where does it go)
CO2 in the atmosphere
Why was there more plants in the past?
There was more light
It may have been slightly warmer
Why are zombie fires so bad for the Arctic?
Lots of carbon dioxide and smoke
Lots of carbon dioxide that speeds up global warming
Creates feedback loops that make zombie fires more likely to happen more often
In cellular respiration oxygen turns into ___________ and sugar turns into ____________
water (H2O)
carbon dioxide (CO2)
What is the goal of photosynthesis?
Plants make themselves food.
What is the relationship between cellular respiration and photosynthesis?
They are opposites
Cellular Respiration:
O2 + C6H12O6 -> CO2 + H2O + energy
Photosynthesis:
CO2 + H2O + energy -> C6H12O6 + O2
In the past, Earth's tilt was ________________
greater
24.1 degrees
Why are they called zombie fires?
Start in the fall, look dead but burn under the snow in the winter, come back in the spring when snow melts
In our experiment, how could we measure more decomposition happening?
There was more foam forming in the beakers
What are the inputs of photosynthesis? (What needs to enter the plant)
Carbon dioxide, Sunlight, Water
What type of energy is sugar?
Chemical Energy
In our experiment, more direct sunlight resulted in ______________.
More oxygen production
More photosynthesis
Why can zombie fires burn more now?
Warmer temperatures are melting permafrost which then makes peat available to burn.
What is the goal of cellular respiration?
To turn food (sugar) into energy
In a strong experiment, all factors in our set up must be kept the same, except for the factor that we are testing. What factors were kept the same in out light intensity experiment?
Same container
Same type of plant
Same amount of plant
Same amount of time tested
Watered the same amount
Name that Law: Energy cannot be created or destroyed, it can only transform from one form to another.
The Law of Conservation of Energy
What factors prevent decomposition? Name 2
Low Oxygen, Low Temperatures
Why is peat a unique fuel source?
It burns hotter and longer than other fuels
It contains high amounts of carbon matter
Name 3 processes that turn sugar into carbon dioxide
Cellular Respiration
Decomposition
Combustion / Burning
Name 3 factors that affect the rate of photosynthesis
Carbon dioxide levels, Water levels, Temperature, Light Intensity, Color of light
How does energy flow through the zombie fire system?
Sunlight -> Plants -> Fire
Light -> Chemical Energy (Sugar) -> Heat
