Question

The rate of decomposition is controlled by

• A. chemical composition of detritus
• B. climatic factor
• C. both a) and b)
• D. nature of detrivores

Answer 1

Answer: (C)

Decomposition is largely oxygen requiring process, rate of decomposition is controlled by chemical composition of detritus and climatic factors. Warm humid condition promotes growth of microbes thus increases rate of decomposition. If detritus is rich in nitrogen and water soluble substance than rate of decomposition is fast, if detritus is rich in lgnin, cellulose than rate of decomposition is slow.
