Which of the following best describes a renewable resource?

A renewable resource is best described as one that can be replenished naturally over time. This means it can regenerate and be used repeatedly without being depleted. Examples include solar energy, wind energy, and biomass, which can continue to be available as long as natural processes or cycles are intact.

In contrast, some alternatives suggest characteristics that do not align with the concept of renewability. For instance, a resource that cannot be replenished would describe non-renewable resources, such as fossil fuels or minerals, which are finite in nature. A resource available in limited quantities also refers to non-renewable resources since it implies a fixed amount that, once used, cannot be replaced. Lastly, while some resources may be consistently in demand (such as energy or water), this demand does not necessarily define whether a resource is renewable or non-renewable—it focuses instead on consumption patterns rather than the ability to regenerate.
