Q. Which of the following is the correct sequence of decomposition processes?

1. Catabolism
2. Fragmentation
3. Leaching
4. Humification
5. Mineralisation

Select the correct answer using the codes given below:
Answer: 2, 3, 1, 4, 5
Notes: The correct sequence of decomposition is: fragmentation, leaching, catabolism, humification, and mineralisation. Fragmentation breaks detritus into smaller pieces; leaching removes soluble nutrients; catabolism degrades organic matter; humification forms humus; and mineralisation releases inorganic nutrients. This sequence is essential for nutrient cycling in ecosystems.
