Option: 2

Fragmentation - Carried out by organisms such as earthworm

Detritus is broken down into smaller particles by detrivores, such as earthworms. The term for this process is fragmentation.

Humification results in the accumulation of humus, a substance with a dark colour and a very slow rate of microbial activity.

Catabolism is the third stage of decomposition, and it takes place in anaerobic conditions through the action of fungi and bacteria.

Through the process of leaching, water-soluble inorganic nutrients precipitate as inaccessible salts into the soil horizon.

Hence, the correct answer is option 2.
