Question

which of these could be a depletable energy resource, if not managed correctly? forests wind solar

Explanation:

Depletable resources can be exhausted if overused without proper management. Wind and solar are renewable and non - depletable as they are natural forces that are essentially inexhaustible on a human timescale. Forests, when used for energy (e.g., wood fuel) without proper reforestation, can be depleted because trees take time to grow back, so if not managed correctly (like over - harvesting without replanting), forests can become a depletable energy resource. Wind and solar energy sources are renewable and not depletable as their energy production is based on natural, continuous processes (wind keeps blowing, sun keeps shining) and their "source" isn't used up in the same way.
