Q. No.Consider the following statements:
The rate of decomposition is high if:
| I: | The detritus is rich in lignin and chitin. |
| II: | The detritus is rich in nitrogen and sugars. |
| III: | The environmental conditions are warm and moist. |
Which of the above statements are true?
| 1. | I and II only | 2. | I and III only |
| 3. | II and III only | 4. | I, II, and III |
Subtopic: Decomposition |

Level 1: 80%+
Hints
Identify the incorrect statements:
| 1. | Decomposition is largely an anaerobic process. |
| 2. | In a particular climatic condition, decomposition rate is slower if detritus is rich in lignin and chitin, and quicker, if detritus is rich in nitrogen and water-soluble substances like sugars. |
| 3. | Warm and moist environment favour decomposition whereas low temperature and anaerobiosis inhibit decomposition. |
| 4. | Detritus is the raw material for decomposition |
