Why do woodlice need cellulase enzymes?

Woodlice require cellulase enzymes to break down cellulose, a major component of plant cell walls, which they consume as part of their diet. These enzymes enable woodlice to efficiently digest and extract nutrients from decaying plant material, aiding in their survival and growth. By facilitating the decomposition process, cellulase also plays a crucial role in nutrient recycling within their ecosystems.
