Please identify this plant

I got a plant/tree as a xmas present but I foolishly threw away the tag not expecting to have problems with. All the leaves are falling off it and I've no idea how to rectify it.

I'd be grateful if someone could identify the type of plant it is and also what I might be doing wrong.

I'll attach a pic of of it

thanks

 

Looks vaguely like some kind of Ficus, bonsai.

 

thanks for the responses.

Yeah light is almost certainly the issue. It was getting any light where I had so I've moved it now and hopefully it will grow its leaves back

 

They can be prone to not tolerating low temperature draughts too so bear that in mind.

In the process of moving house a few years ago some of my plants went to SWMBO's mother who turns out popped them in the brightest spot she could find...next to an external door which she nearly always left open. They came back nicely though after their holiday in the wind tunnel
