Solution
The correct option is D Fragmentation
Earthworms eat soil and also excrete soil as small pellets. During the passage of soil through their alimentary canal, the decaying matter is broken down into small particles or fragments. This process is called fragmentation. It facilitates faster degradation of the small fragments by the soil microflora.
