Technically, nothing is composed *only* of organic material.
* Organic material refers to substances containing carbon-hydrogen bonds, usually derived from living organisms.
* All living things, including plants and animals, are composed of both organic and inorganic materials. Inorganic materials like water, minerals, and salts are essential for life processes.
Here's an example:
* A tree trunk is mainly made of organic material like cellulose and lignin.
* However, it also contains inorganic material like water, minerals, and trace elements.
So, what things are mostly composed of organic material?
* Living organisms (plants, animals, fungi, bacteria)
* Biodegradable materials (food scraps, paper, wood)
* Fossil fuels (coal, oil, natural gas) - formed from ancient organic matter
* Humus in soil - decomposed organic matter
It's important to remember:
* The definition of "organic" can be broader in some contexts (like organic farming), referring to materials produced without synthetic pesticides or fertilizers.
* Even substances we think of as organic, like cotton, are treated with inorganic chemicals during processing.
