Tag: Non living things

While most of our diet consists of items derived from living organisms, humans regularly consume substances that were never alive. Water and salt are two common examples of non-living things that are vital for human survival and play indispensable roles in our physiology.

As heterotrophs, humans rely on organic, once-living matter for energy. This fundamental biological reality leads to the question: **Is it possible to humans eat non-living things?** The answer, rooted in our cellular biochemistry, reveals why consuming inanimate objects is not a source of nutrition.
