Question
Observe the contents 1, 2, 3 and 4 of soil samples A, B and C shown in the graph. If the temperature and soil moisture of all soil samples are identical, which soil sample (s) will show faster decomposition?
1 indicates lignin content, 2 indicates chitin, 3 indicates nitrogen content, and 4 indicates sugar content
Options
Soil Sample A
Soil Sample B
Soil Samples A and B both
Soil Sample C
Solution
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.
