Which of the following is the correct order of steps in decomposition of detritus?

Answer: Fragmentation, leaching, catabolism, humification and mineralisation.

  • A Fragmentation, leaching, catabolism, humification and mineralisation
  • B Humification, fragmentation, leaching, catabolism
  • C Leaching, mineralisation, fragmentation, catabolism and humification
  • D Catabolism, humification, leaching, fragmentation

Correct answer: A. Fragmentation, leaching, catabolism, humification and mineralisation

Explanation: Decomposition proceeds through fragmentation of detritus, leaching of soluble nutrients, catabolism by enzymes, then humification and mineralisation.
