Understand the definition of a mineral: A mineral is a naturally occurring, inorganic solid with a definite chemical composition and an ordered atomic arrangement (crystalline structure).
Analyze the properties of table sugar: It is a crystalline solid, has a definite chemical composition, and is soluble in water.
Identify the key difference: Table sugar is produced by living organisms (plants), which means it is organic in origin.
Compare this to the mineral definition: Since minerals must be inorganic, substances produced by living organisms do not qualify as minerals.
Conclude that table sugar is not a mineral because it is produced by living organisms, making it organic rather than inorganic.
