The process of decomposition delays when
- A the detritus is made up of sugars and nitrogen compounds
- B aeration is sufficient
- C warm and moist environment exists
- D detritus is rich in lignin and chitin.
Answer & Solution
Correct Answer
(D) detritus is rich in lignin and chitin.
Step-by-step Solution
Detailed explanation
(D) detritus is rich in lignin and chitin.,
The complex organic nutrients in dead organic matter are broken down into inorganic substances like carbon dioxide, water and nutrients by a process known as decomposition.
The rate of decomposition is slower if detritus is rich in lignin and chitin and faster if detritus is rich in nitrogen and water-soluble substance like sugars.
