उत्तर
Soil Sample C
Explanation:
Decomposition is the conversion of organic material into basic inorganic material. The pace of decomposition varies under the same environmental conditions as a result of variations in detritus composition. The pace of decomposition is sluggish if the debris contains a lot of lignin and chitin. Nitrogen-rich detritus has a relatively high breakdown rate. As a result of the detritus' high nitrogen and sugar content, the breakdown rate in soil sample C will be faster.
