Wood is considered organic. This classification arises from its composition, as wood is derived from trees, which are living organisms. Organic materials are primarily made up of carbon-based compounds, and wood is mainly composed of cellulose, hemicellulose, and lignin, all of which are organic compounds.
Moreover, organic materials are those that originate from living organisms or contain carbon-hydrogen bonds, both of which are characteristic of wood. In contrast, inorganic materials typically include minerals and metals that do not have carbon-hydrogen structures.
Hence, since wood comes from trees, which are very much a part of the biological world, it is classified as an organic material.
