Consider a bacteria community feeding on some fallen leaves. The bacteria has a C:N ratio of 10 while the fallen leaves have a C:N ratio of 50. What nutrient cycling process would happen when bacteria is consuming the leaves? And how much nitrogen would be transformed through the process when 100 grams of leaf carbon is consumed that led to 40 grams of increase in bacteria carbon (due to production efficiency), assuming perfect utilization of nitrogen by the bacteria?

Group of answer choices

A: Immobilization, 8 grams of nitrogen

B: Immobilization, 2 grams nitrogen

C: Mineralization, 8 grams nitrogen

D: Mineralization, 2 grams nitrogen

E: None of the Above is correct
