First, explore the interactions in the carbon cycle "PATH".

What is being shown by the purple arrow?

This image shows carbon dioxide moving from _____________________________________________.

This image shows movement of carbon through ____________________________.

Next, click on the "MODEL" tab. 

Make sure that "Show values" is selected. 
Do not change any of the slides except for the "Plant Biomass" slide. (Biomass is the stored chemical energy from the sun. Plants produce this biomass through photosynthesis)

Change the Plant biomass slide to make observations about how changes in the plant biomass affect the atmospheric CO2 levels. 

ADVANCE TIME MANUALLY BY CLICKING "10 YEARS" TO SEE HOW THE CHANGES IMPACT ATMOSPHERIC CO2

The image below shows what the  simulation looks like with original settings after 10 years. Us this image to compare your answers.

Based on the MODEL simulation of the carbon cycle, what happens when you decrease the plant biomass?

Based on the MODEL simulation of the carbon cycle, what happens when you increase the plant biomass?

Create a Model.
Must be original work

Create a model: That shows how a carbon moves through the atmosphere, biosphere, geosphere and hydrosphere. Show the interaction of cellular respiration and photosynthesis in your model as well.
Make sure that you label the spheres and indicate where photosynthesis is taking place to get credit for your work.
For this model, you should draw the carbon cycle

Make sure you label the hydropshere, geoshpere, biosphere and atomosphere.
Label photosynthesis and cellular respiration.

Must be original work

Consider: If we wanted to decrease overall atmospheric CO2, how could we use the mechanisms of cellular respiration and photosynthesis to do this?
