Answer 2

Here we must use the auxiliary verbs.

Hence the statement after adding the question tag must be following - They are breeding grounds for the germs aren’t they?

The auxiliary verb is referred as the verb which adds the grammatical or functional meaning to that clause in which the verb appears.

It is used to express the aspect, emphasis, tense, voice etc.

These verbs accompany the main verbs.
