Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Decomposition has the steps fragmentation, leaching, catabolism and humification, in that order.
Step 2: Steps
Fragmentation (B): detritivores break detritus into small pieces.
Leaching (D): soluble nutrients seep into the soil.
Catabolism (C): enzymes of bacteria and fungi break detritus into simple substances.
Humification (A): dark humus accumulates.
Step 3: Select
The order is B, D, C, A.
Final Answer:
The correct order is B, D, C, A. \[ \boxed{\text{(D) }B \rightarrow D \rightarrow C \rightarrow A} \]
