Understanding RMAN Level 0 and Level 1 Backups in Database Administration

DBA Interview Question: Without RMAN Level 0 , Can it be taken RMAN Level 1 Backup? then what happens?
In above pic, We initiated level 1 incremental backup. but says no parent backup or copy of datafiles. then it started taking Level 0 backup the Base Backup.
So if no level 0 backup , then level 1 will initiate level 0 backup.
Syntax :
rman>backup incremental level 1 database;
For level 0 incremental backup
rman>backup incremental level 0 database;
