What is starvation in fire?

Can you please clarify what is meant by the term 'starvation in fire'? Is it a reference to a specific phenomenon related to fires, or is it a metaphorical expression? If it refers to a physical occurrence, what are the conditions under which this starvation occurs, and how does it impact the behavior and progression of a fire? Alternatively, if it's a metaphor, could you provide some context or examples to help me better understand its meaning? I'm eager to learn more about this concept and how it relates to the study of fire and its effects.
