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.

Do the above statements mean one and the same thing. If your answer is yes, give reasons. And if your answer is ‘no’ explain the meaning of each expression.
Assertion (A): Decomposition process is slower if detritus is rich in lignin and cutin.
Reason (R): Decomposition is largely an oxygen requiring process.
Identify the correct statements:
- Detrivores perform fragmentation.
- The humus is further degraded by some microbes during mineralization.
- Water soluble inorganic nutrients go down into the soil and get precipitated by a process called leaching.
- The detritus food chain begins with living organisms.
- Earthworms break down detritus into smaller particles by a process called catabolism.
