A rotting log is a mighty tasty meal—if you're a termite. Termites not only eat wood, some kinds live in it, too. Termites are social insects. This doesn't mean that they like to talk a lot—it means that each member of the colony has an important job. Workers gather food, soldiers protect the nest and attack intruders, and the king and queen produce thousands of new termites each year.
