Source Sugar Flour Pepper Salt Sugar Cane Wheat Seeds Pepper Seeds Ocean/lakes In conclusion: Substances that make living things, also burn. What does “burning” mean? A substance that burns, does this: Initial heat CO2 +H2O+heat Since it breaks down to carbon dioxide and water, the substance must contain carbon. ORGANIC substances are made out of C, H, and sometimes O, N, more. Organic substances burn. Substance + O2 Organic substances: •In nature, they originate from living organisms. (Today – many are synthetic).

Proteins (amino acids) Carbohydrates (mono- disaccharides) Lipids Nucleic acids (nucleotides) Proteins are made of amino acids. There are 20 different amino acids, but all share the following part: I SPY amino acids! O N O Carbohydrates are made of small sugars, singular or in chains. Small sugars can look like a ring or an open ring: I SPY carbohydrates!
