My Name is chris and I am from Malta nice to meet you all

I have had my bonsai for some months now and I am noticing that its loosing its leaves. its on a window sill and I water it when soil feels less damp.
first of all I would like to identify if its real or not and what species it is so I can learn how to take care of it.
I Live in malta and our sun is very strong.
thanks for your help.
