Of course.
The way I understand it, "consumes" does not mean the resource is gone, only that it is used to calculate the benefit.
Example:
Let's say you have Sid's Sushi Co. (consumes rice, fish, crab and clam; grants 0.50
and 2
per resource consumed).
The city with corporation has resources connected as follows (they do not need to be in fat cross):
- rice (2)
- fish (3)
- clam (1).
This means that city is getting extra 3
(6x0.5) and extra 12
(6x2).
This does not mean the resources are gone (and I suspect you still get +3
in that city from having 3 different food resources).
However, if you lose or otherwise trade away some of the resources, the bonus from corporation will go down appropriately.
