Termites are social insects that feed exclusively on plant material.
They occur in vast numbers in tropical regions, where they are probably the most important animals contributing to decomposition processes. Many termite species are voracious consumers of wood, and some of these are highly destructive pests of wooden buildings and furniture, plantation trees and crops. However, most termite species are innocent inhabitants of tropical forests, and have a positive effect on soil fertility. They and their nests also provide food and shelter for an extraordinary number of associated organisms. Despite their importance, little is known about the evolution, diversity and general natural history of termites, or how this influences their role in ecosystems.
