To avoid taking those extra steps, expert composters might add extra wood chips or paper products to the pile, since they have a lot of lignin — a tough component of plant cell walls which doesn't contain any nitrogen at all.
为了避免这些额外的步骤,专业的堆肥者能会往堆肥中再加入一些木屑或者纸质品,因为它们含有大量木质素,一种完全不含氮的坚韧的植物细胞壁成分。
Insects like termites can go whole hog on the whole log, because they can " chew" the wood with their serrated mandibles AND also have the right gut machinery - AKA microbes - to break the lignin down on the molecular level.
像白蚁这样的昆虫以吃掉整根原木,因为它们以用锯齿状的下颚“咀嚼” 木材,并且还有合适的肠道机制——也就是微生物——在分子水平上分解木质素。
