Question

Process of decomposition
Choose answer:
Does not involve activity of saprophytic microorganisms.
Is better in cold and dry soil.
Is faster if detritus does not contain lignin, tannin, cellulose etc.
Occurs only in anaerobic conditions.

Answer 1

Answer:

b

Explanation:

because is better in cold and dry soil helps in decomposition

Answer 2

Decomposition process

Explanation:

Process of decomposition is faster if detritus does not contain lignin, tannin, cellulose etc

• If detritus contains tannin,lignin and cellulose then it takes a longer time to decompose because of the high C:N ratio
• Decomposition includes the activity of saprophytic microorganisms Saprophytes live and feed on dead and decaying organisms and  break down the complex organic matter into simpler substances that are taken up by the plants for various metabolic activities
• Decomposition rates are low under very wet or very dry conditions and are highest in damp, moist conditions with adequate levels of oxygen; Wet soils tend to become deficient in oxygen (this is especially true in wetlands), which slows microbial growth
• Decomposition occurs in both aerobic and anaerobic conditions;the process is quite slow in case of anaerobic condition
