Factor Affecting Decomposition Effect on Decomposition A. Low temperature and anaerobic conditions 1. Slows down decomposition rate B. Rich in nitrogen and water-soluble substances 2. Speeds up decomposition rate C. Warm and moist environment 3. Favors rapid decomposition D.Rich in lignin and chitin 4. Inhibits decomposition

Options

  1. AA - 4, B - 2, C - 3, D - 1
  2. BA - 2, B - 3, C - 1, D - 4
  3. CA - 4, B - 1, C - 2, D - 3
  4. DA - 3, B - 2, C - 4, D - 1

Correct answer

A. A - 4, B - 2, C - 3, D - 1

Step-by-step solution

Detritus rich in lignin and chitin (D) tends to slow down decomposition rate (1). Detritus rich in nitrogen and water-soluble substances (B) speeds up decomposition rate (2). A warm and moist environment (C) favors rapid decomposition (3). Low temperature and anaerobic conditions (A) inhibit decomposition (4).
