In the last sentence, the adverb 'quickly' gives us more information about what happened - it 'qualifies' or 'modifies' the verb.

If a dog takes a long time to eat the bone, we would say:
The dog slowly ate the bone. -or- The dog ate the bone slowly.

An adverb indicates 'when', 'how', or 'where' something happens.

The girl ran.
How did she run? She ran quickly.
When did she run? She ran yesterday.
Where did she run? She ran through the field.

As you can see, an adverb doesn't always end in -ly, and a clause (through the field) can act as an adverb (this is called an adverbial clause).
