The < is a re-direct operator just like the >. < means take input from this
file and the > means send to this file. You probably know this, so what you
might really be asking is why is it needed when sometimes the command will
work without it?  Often one or the other of these re-directors is built into
or assumed by the command... sometimes based on argument position or
whatever. I like to always use them whether they are needed or not to keep
things very readable.
