Question

Which one of the following is a common way to measure decomposition rate?

a) Amount of detritus present in an environment at any one time, measured by weighing detritus in the field at any one time.

b) Rate of NPP in the same habitat, measured by estimating plant biomass change over time.

c) Change in the amount of detritus over time, measured by having a weight of detritus on one date and then on several subsequent dates, often months apart.

d) Biomass of decomposers, measured by sampling and weighing decomposers in the field.

Explanation / Answer

Ans)C

This method is known as Litterbag method and it is most commonly used.Litter bags are installed at places and the change in weight of litter or weight of detritus gives the decomposition rate..So,decomposition rate is measured by the change in amount of detritus over time measured by having the weight of detritus on one date and then on several subsequent dates,often months apart.Since decomposition is a slow process so it may take months.
