Identify the correct statement about decomposition -
(A) The rate of decomposition is quicker, if detritus is rich in nitrogen and sugar.
(B) Decomposition is largely an oxygen requiring process.
(C) The rate of decomposition is slow, if detritus is rich in chitin and lignin.
(D) The rate of decomposition is slow, if detritus is rich in nitrogen and sugar.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A), (B) and (C) Only
(A) The rate of decomposition is quicker, if detritus is rich in nitrogen and sugar. — True.
(B) Decomposition is largely an oxygen requiring process. — True.
(C) The rate of decomposition is slow, if detritus is rich in chitin and lignin. — True.
(D) The rate of decomposition is slow, if detritus is rich in nitrogen and sugar. — False. Nitrogen and sugars make it quicker.
NCERT Extract:
Decomposition – “… Decomposition is largely an oxygen-requiring process. The rate of decomposition is controlled by chemical composition of detritus and climatic factors. 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.”
