Answer:
B. The biomass of leaf litter in the bags will be greater in leaves with higher lignin content after the same length of time.
Explanation:
Lignin is a major, one of the most slowly decomposing components of dead vegetation, including leaf litters. The lignin content has been found to have a high correlation with litter decomposition.
<em>Hence, at the end of the experiment, the litter bag containing leaf litters with higher lignin contents will be expected to weigh more than those with lower lignin contents.</em>
The correct option is B.
