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 |
