Why does dehydrated food last longer?

How does dehydrating food make it last longer? Freeze drying and dehydration prevents the growth of fungus, mold, bacteria, and other microbes that cause vegetables (and other foods) to spoil. It is the lack of water content in our dried vegetables that keeps them safe to eat for so long.

What is the purpose of dehydrating food?
