Knowra Xylophagy Xylophagy Xylophagy is the consumption of wood as food. It is found in insects and other animals, often with microbial help to break down wood’s cellulose and lignin.
Cellulose digestion : The enzymatic breakdown of cellulose into smaller sugars that organisms can absorb or use. Wood-feeding animals must access energy locked in cellulose, a major component of wood.
Termite : A social insect in the order Blattodea, many species of which feed on wood or other plant material. Termites are among the best-known animals whose diets include substantial amounts of wood.
Wood : The fibrous structural tissue of trees and other woody plants, composed mainly of cellulose, hemicellulose, and lignin. It is the material consumed in xylophagy and the source of its distinctive digestive challenge.
Detritivore : An organism that obtains nutrients by consuming dead organic matter. Many wood-feeding animals consume dead timber, placing their feeding within detrital food webs.
Wood decomposition : The physical and biological breakdown of wood into simpler compounds and materials. Xylophagous animals fragment and digest wood, contributing to its decomposition.
Lignin degradation : The chemical breakdown of lignin, a complex polymer that strengthens plant cell walls and resists decay. Lignin shields wood’s digestible carbohydrates and can limit what wood-feeding animals extract.
Shipworm : A marine bivalve mollusk that burrows into and often consumes submerged wood. Shipworms are mollusks, not worms, and independently evolved a wood-based feeding strategy.
Cellulose : A structural polysaccharide made of glucose units and a major component of plant cell walls. Its abundance makes cellulose a major potential energy source in wood.
Xylophagy in marine ecosystems : The ecological use of sunken wood by organisms that colonize and consume it on the seafloor. Marine wood falls support specialized wood-feeding communities far from forests.
Carbon cycle : The movement of carbon among organisms, the atmosphere, oceans, and geological reservoirs. Wood consumption redirects stored plant carbon through animal and microbial food webs.
