Q. Consider the following statements regarding decomposition:
1.Detritivores break down detritus into smaller particles.
2.Bacterial and fungal enzymes degrade detritus into simpler inorganic substances is called as catabolism.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C
Notes:

Explanation: Detritivores (e.g., earthworm) break down detritus into smaller particles. This process is called fragmentation.

  • By the process of leaching, water soluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts.
  • Bacterial and fungal enzymes degrade detritus into simpler inorganic substances. This process is called as catabolism.
