What describes cellulose and hemicellulose in terms of decomposition rate?

Cellulose and hemicellulose are polysaccharides found in plant cell walls that play significant roles in decomposition and nutrient cycling. The correct answer points out that these compounds decompose at a moderate rate due to their complexity.

Cellulose, which is the main component of the cell wall, has a highly structured and crystalline form that makes it more resistant to microbial attack compared to simpler sugars. Although cellulose can be broken down by specific microorganisms, the process is not as quick as the decomposition of simpler organic materials. Hemicellulose, which is branched and has a more varied structure than cellulose, may break down more readily than cellulose but still does not decompose as rapidly as simpler compounds like simple sugars.

Both cellulose and hemicellulose contribute to the carbon pool in soils and affect overall nutrient cycling and soil health, emphasizing their importance in ecosystems. Their moderate decomposition rates lead to a gradual release of nutrients, supporting soil fertility over time.
