Step-by-step explanation:
Nonexpendable refers to something that cannot be exhausted, depleted, or used up.
In the context of resources, nonexpendable can be understood as a resource that exists in a fixed amount and cannot be replenished or replaced. Nonexpendable resources may include fossil fuels, precious metals, or minerals.
For example, crude oil is a nonexpendable resource because it is finite and cannot be reproduced. Once it is extracted and used, it cannot be replenished in a short period of time.
