Question

Which chemical composition of detritus favours rapid decomposition?

विकल्प

• Detritus rich in nitrogen and water-soluble substances such as simple sugars and proteins

• Detritus with low nitrogen and high chitin content

• Detritus rich in lignin and chitin

• Detritus rich in cellulose and structural compounds

Answer 1

Decomposition is faster when detritus contains high levels of nitrogen and water-soluble substances like simple sugars and proteins. These components are readily utilised by decomposers and are easily broken down. In contrast, lignin (found in plant cell walls) and chitin (found in fungal walls and insect exoskeletons) resist microbial degradation and slow decomposition.
