Detailed Solution

A is true, R is false.

Assertion (A) is true; decomposition rates generally increase with higher temperatures and in environments with adequate nitrogen and moisture.
Reason (R) is false; decomposition rate is typically slower for detritus rich in lignin and chitin because these compounds are more resistant to decomposition. In fact, detritus with higher lignin and chitin content tends to decompose more slowly compared to detritus with lower lignin and chitin content.
