Detailed explanation-1: -Nutritional Types of Microorganisms All microbes have a need for three things: carbon, energy, and electrons. There are specific terms associated with the source of each of these items, to help define organisms.
Detailed explanation-2: -The trace elements tungsten and molybdenum play an essential role in the growth of anaerobic microorganisms.
Detailed explanation-3: -As metal ions, the trace elements usually act as cofactors for essential enzymatic reactions in the cell. One organism’s trace element may be another’s required element and vice-versa, but the usual cations that qualify as trace elements in bacterial nutrition are Mn, Co, Zn, Cu, and Mo.
Detailed explanation-4: -Micronutrients are molecules we need in small quantities (but equally as important), such as vitamins and minerals. Words to know: Nutrient: a dietary component that can be used by the body to stay healthy. Molecule: a chemical term for a structure that is larger than an atom but smaller than a cell.
