Problem:
Describe the answer of all the questions:
Question 1: What is the thinking behind cross-site studies? Why is it likely that these studies have not found a relationship between SOM decomposition and temperature?
Question 2: What are the components of the new model they are proposing? Why is important that they differentiate these different processes?
Question 3: Increased temperatures may cause microbes to make more exo-enzymes or less exo-enzymes. Describe the hypotheses that are behind both of these predictions.
Question 4: What is the best explanation for how the temperature sensitivity of exo-enzymes change seasonally?
Question 5: Why does microbial growth efficiency matter with regard to SOM changes?
Question 6: How could microbial growth efficiency be measured? What do previous studies suggest about how temperature affects microbial growth efficiency? What are the possible hypotheses to explain these results?
Question 7: The authors discuss 2 broad types of reactions that affect adsorption of OM to soil. What are these and how does a temperature increase affect these processes?
Question 8: he authors suggest that temperature and soil moisture will affect other factors that will affect decomposition rates - what are these factors?
Please give discription of all the questions.
