What is the difference between a sapsucker and a woodpecker?

What do sapsuckers do to trees?
Sapsuckers drill numerous rows of 1/4 - 3/8 inch closely spaced holes in healthy trees to feed on sap and the insects entrapped by the sap. They may feed on ornamental or fruit trees. Holes may be enlarged through continued pecking or limb growth, and large patches of bark may be removed or sloughed off.
What causes tree cavities?
Description: Tree cavities are often the result of an injury followed by decay. Decay can begin by injury to the trunk, the loss of a large limb, topping or improper pruning. The inner dead wood begins to decay but living wood is protected by a barrier zone that compartmentalizes damage.
