Decomposition Reaction

Knowledge Check

  • Fragmentation, leaching and catabolism are some of the important steps of decomposition. Study the following statements I , ii and iii regarding these and select the correct option. (i) Detritivores (e.g., earthworm) breakdown detritus into smaller particles. (ii) Water soluble inorganic nutrients go down into soil horizon and get precipitated as unavailable salts. (iii) Decomposers (e.g., bacteria and fungi) secrete digestive enzymes and degrade detritus into simpler inorganic substances.
