Important to the structural integrity of plant cells, but NOT a polysaccharide (chain of sugars):
Chitin
Lignin
Cellulose
Hemi-cellulose
Important to the structural integrity of plant cells, this polysaccharide (chain of sugars) links cellulose and lignin:
Peptidoglycan
Protein
Chitin
Hemi-cellulose
Which of these is likely to be converted to CO2 the slowest?
Soluble carbohydrates
Cellulose
Lignin
These all get converted to CO2 at the same rate
Important to the structural integrity of plant cells and comprised of the reaction product from photosynthesis, this is the single most common polysaccharide (chain of sugars) in the world.
Hemi-Cellulose
Lignin
Cellulose
Chitin
Which of these does not require enzymatic depolymerization and is therefore likely to be converted to CO2 the fastest?
Simple sugars
Cellulose
Lignin
Hemi-cellulose
A soil's ability to retain organic matter is first and foremost a function of its:
Age
Parent Material

Climate
Which of these is likely to be converted to CO2 the slowest?
Root exudates
Deciduous leaves
Wood
Roots
At the global scale, across regions with variable precipitation, which climate variable is likely to be the best correlated with plant litter mass loss rates during the first year of decomposition?
actual evapotranspiration rates
precipitation
potential evapotranspiration rates
soil temperature
