Passive Tense

[Sambodia]

Hello,
Is the passive tense the same for Present Continuous and Present Perfect Continuous?
For example:

Present continuous:
The food is being eaten

Present perfect continuous:
The food is beeing eaten

Thanks a lot

The passive is a mood, not a tense.

Present continuous: The food is being eaten
Present perfect continuous: The food has been being eaten

We use the present perfect continuous passive form extremely rarely. We prefer either the active continuous or the the passsive non-continuous form.
