You perform an experiment to compare the breakdown rate of leaves of four tree species. Species A has a solubility of 3 mg C/g dry leaf and a lignin/nitrogen ratio of 4:1. Species B has a solubility of 15 mg C/g dry leaf and a lignin/nitrogen ratio of 3:1. Species C has a solubility of 8 mg C/g dry leaf and a lignin/nitrogen ratio of 1:1. Species D has a solubility of 1 mg C/g dry leaf and a lignin/nitrogen ratio of 2:1. Which species would you expect to have the fastest decay rate within the first 50 days (first answer), and which species do you predict will have the fastest decay rate after 50 days (second answer)
