But a group is no organism physically added to its constituent individuals; it has no brain or stomach of its own; it must think or feel with the brains or nerves of its members. 但是，群体除了是由单个的人组成外，并不是真正具有生理作用的有机体，它没有自己的大脑和肠胃；它必须依靠其成员的大脑和神经，进行思考与感知。
请问文中的physically（ added）是修饰哪个成分？断句应该是 no organism physically / added to its constituent individuals还是 no organism / physically added to its constituent individuals。如果是后者的话，书中的翻译是不是有问题？
