👉 The term "autochemical" refers to a chemical that is derived from natural sources and has not been chemically synthesized. This type of chemical can be found in plants, animals, fungi, bacteria, or other living organisms. Some examples of autochemicals include: - Nitrogen fixation: This process occurs when soil organisms use nitrogen from the air and decompose organic matter to produce glucose. - Pyruvate fermentation: In this process, pyruvate is converted into lactic acid
