It is what ever you define them as

L0 is usually the service desk with very little skills on any subject or technical area
L1 usually has a working knowledge of the technical or functional area
L2 - More knowledge - senior people who may have years
L3 - more and may be the vendor itself
L4 like L3


it is up to the organisation to define who does what

It is like a hospital visit

You come to the receptionist (L0)
The nurse may take information and take your pulse, and BP (L1)
The resident on duty will interview and work to determine if any specialist is needed and try to 'fix' your issue or escalate to the next level (L2)
The surgeon / specialist would look at critic issues ythat L2 can not do - Surgery etc
