What is a characteristic of a renewable resource?

A renewable resource is characterized by its ability to regenerate or replenish itself naturally over time, making it sustainable for long-term use. This characteristic ensures that such resources will not run out in the foreseeable future as they can be replaced at a rate equal to or greater than the rate at which they are consumed. Examples include solar energy, wind energy, and biomass, all of which continuously generate or are replenished through natural processes.

In contrast, the other options describe qualities that do not align with the definition of renewable resources. For example, the idea of being completely depleted or having a finite amount directly contradicts the renewable nature of these resources. Additionally, being toxic does not relate to the renewable characteristic, as some renewable resources can indeed be non-toxic and environmentally friendly. Thus, the essence of a renewable resource lies in its sustainability and long-term availability, rather than being finite, toxic, or easily depleted.
