Trees are consumed in whole or in part by termites and other wood-feeding insects, beavers, giraffes, elephants, rabbits, rats, and porcupines. Insects that eat wood are among the most dangerous and serious wood consumers since they can consume thousands of trees and tonnes of lumber each year.
Termites are some of the world’s most voracious wood eaters. Wood waste is also consumed by bark beetles and wood borers.
Animals with specialised digestive systems that consume wood and bark of trees turn to trees for food. Particularly beavers rely on woody flora for their meals, but during the winter when food is short, they typically consume bark.
The outer and inner bark, leaves, and twigs of woody plants, as well as the branches of trees, are all consumed by giraffes, elephants, rabbits, rats, and porcupines, but not the entire tree.
