Which one of the following options represents the steps of decomposition in sequence?

Options

  1. AFragmentation Humification Leaching Catabolism Mineralization
  2. BFragmentation Leaching Catabolism Humification Mineralization
  3. CFragmentation Humification Mineralization Leaching Catabolism
  4. DFragmentation Catabolism Humification Mineralization Leaching

Correct answer

B. Fragmentation Leaching Catabolism Humification Mineralization

Step-by-step solution

Decomposition is the process of breaking down complex organic matter into simpler inorganic substances like carbon dioxide, water, and nutrients. The important steps in the process of decomposition occur in the following sequence: Fragmentation: Breakdown of detritus into smaller particles by detritivores. Leaching: Water-soluble inorganic nutrients seep into the soil horizon and precipitate as unavailable salts. Catabolism: Bacterial and fungal enzymes degrade detritus into simpler inorganic substances. Humificati
