Lignin

Vedclass · Answer

(A) The rate of decomposition is controlled by the chemical composition of detritus and climatic factors. Decomposition is slower if detritus is rich in lignin and chitin,as these are complex,recalcitrant organic compounds that are difficult for microorganisms to break down. Conversely,decomposition is faster if detritus is rich in nitrogen and water-soluble substances like sugars. Therefore,the correct option is $A$.

List-$I$	List-$II$
$A$. Decomposition	$I$. Accumulation of dark coloured amorphous colloidal substance
$B$. Detritus	$II$. Release of inorganic nutrients by the activity of microbes in soil
$C$. Mineralisation	$III$. Breaking down of complex organic matter into inorganic substances
$D$. Humification	$IV$. Dead remains of plants and animals including fecal matter
