Please Identify My Tree?

I found this tree on the sidewalk and took it home (it was in a bag and looked decent enough to take home), I dont know what kind of tree it is, therefore dont know how to tend for it. I would love if you could help me out and tell me how to take care of it. and if that shrub on the bottom is supposed to be there?
Thank you so much!

Hi Dani,

Your tree is a Braided Ficus Tree. There are care instructions in the Popular HousePlantSection of the website. Ficus trees lose leaves when moved to a new location or when they are in a cold draft. Yellow leaves develop when the ficus tree needs more water; green leaves fall off when the ficus tree is over watered.
