inorganic substances, such as water, mineral salts, molecular oxygen and carbon dioxide, are small molecules made up of few atoms. Organic substances, in general, such as glucose, fatty acids and proteins, are much more complex molecules made of sequences of carbons bound in carbon chains. The capacity of carbon to form chains is one of the main chemical facts that allowed for the emergence of life on the planet.

Detailed explanation-1: -Answer and Explanation: All living organisms are made up of molecules that can be organic or inorganic. The organic molecules are mainly composed of carbon, hydrogen, and oxygen. The inorganic molecules are mainly a molecular form of elements like oxygen, sulfur, phosphorous, zinc, iron, and so on.
Detailed explanation-2: -Plants and plant products, the proteins and fat that make up our bodies, as well as our DNA, are all examples of organic molecules. Salts, metals, and related chemicals are examples of inorganic compounds.
Detailed explanation-3: -Answer and Explanation: Difference between organic and inorganic molecules: Organic compounds are made up of at least one bond between carbon and hydrogen, whereas in the inorganic compound there is no need for such bonding.
