When does the flex-grow switch become flexible and vice versa?

Question

I don’t understand what causes flex items to go from growing to reduce behavior? At first I thought it was a value flex-basis, but what if only one element has it or not?

In addition, the specifications on flex-basissay:

The flex-based CSS property is based on flex, which is the initial base size of the flex element.

What does it mean? If I have one element with it, and the rest by default, why does it usually start a little more than the value? Where is the added space added from?
