Summarize the feedback loop (transfer of energy) between the microbes and the mushrooms. (Video #1)
What is the Nitrogen Cycle? Discuss the 3 types of microbes required for the nitrogen cycle. What would happen to the soil if the microbes were not there?(Video #2)
Where and how does carbon move? How do plants help recycle CO2? Where do plants get their CO2 from? (Video #3)
Scientists are wondering how soil and soil microbes interact, how they will respond to global warming, specifically what will happen to the levels of CO2 and CH4 if the soil warms up.

Analyze the Results from this student’s data (Links to an external site.)
Based on these results, (1) would the warming of the climate cause an increase or a decrease in soil respiration? Use data to back up your claim. (2) How might this impact the environment?
