Which term applies to all living things and those things that were once alive?

1. Organic

2. Inorganic

3. Synthetic

4. Natural

The correct answer is: Organic

The term that applies to all living things and those things that were once alive is "organic." This classification is based on the presence of carbon compounds, which are the fundamental building blocks of life. Organic materials include all living organisms, as well as the remnants of any organisms that have died, such as fallen leaves, decomposed plants, and animal remains. In contrast, inorganic refers to materials or substances that do not originate from living organisms, such as minerals and metals, which helps to differentiate them from organic substances. Synthetic materials are artificially created compounds, typically through chemical processes, and do not involve any biological origin. Natural refers to substances that are found in nature without human alteration, but does not necessarily encompass the encompassing scope of all living things and their remnants. Thus, organic is the most accurate term that captures both living and once-living entities.
