Natural:
* Rocks: These are formed from minerals and don't have the characteristics of life.
* Water: While essential for life, water itself is not a living organism.
* Air: A mixture of gases (nitrogen, oxygen, etc.) that does not possess the qualities of life.
* Sunlight: Provides energy for life but is not alive itself.
* Soil: A combination of minerals, organic matter, and microorganisms, but it's not a living organism.
* Mountains: Geologic formations created by tectonic activity.
* Volcanoes: Geothermal vents that release heat and rock from the Earth's mantle.
Man-made:
* Buildings: Structures made of concrete, steel, and other materials.
* Cars: Machines designed for transportation.
* Computers: Electronic devices that process information.
* Plastic: A synthetic material not derived from living organisms.
* Metal: Elements like iron, gold, and aluminum are not alive.
Key Concept: Biotic factors are living things, while abiotic factors are non-living components of the environment.
