How is the rate of decomposition affected by the nature of detritus and temperature ?
Marking-scheme solution
• Detritus rich in lignin and chitin– slow decomposition, rich in nitrogen and water
soluble substances like sugar – decomposition rate is faster,
• Warm environment – favour decomposition, low temperature – inhibit
decomposition.
