I don't quite understand how one should use the expression "exported from somewhere". What does it mean when an item is exported from a given place?
So far I've always seen the verb export used like this:
The UK exports veal to many European countries.
I've also seen the verb import being used like this:
The UK imports asparagus from Bolivia.
But I don't understand what exported from means. For example:
Wheat is exported from the UK.
