Fresh air is an example of a/n A. sustainable yield.
B. non-renewable resource.
C. incorporated resource.
D. renewable resource.

Answers

The question is asking us to choose what kind of resource fresh air is. Fresh air is mostly just the air that is being in our athmosphere (when we don't polute it).

Renewable resource.

As we already know, this is the function of the kidneys and the rest of the renal system.
