Decomposition is slower when detritus is rich in:
ANitrogen and salt
BStarch and sugar
CLignin and chitin
DSugars and water
Answer & Solution
Correct answer: C. Lignin and chitin
1. Chemical composition of detritus sets the pace.
2. Nitrogen and soluble sugars speed decomposition up.
3. Lignin and chitin slow it down.
