Concept of a resource; resource classifications: stock and flow resources
A resource is anything humans extract value from to meet their needs. Resources split into two types: stock resources run out when used, while flow resources naturally replenish themselves.
Real World
Saudi Arabia's oil fields are a stock resource — once extracted, the crude oil cannot be replaced. The River Thames is a flow resource: rainfall continuously replenishes it, making it usable indefinitely if managed correctly.
