Final answer:
Bacteria A, being 'met-' and 'bio-', needs specific metabolic precursors and growth factors, including vitamins, to grow. A suitable physical environment with the right temperature, pH, and oxygen concentration is also crucial for its growth.
Step-by-step explanation:
Bacteria A is "met-" and "bio-" indicating that it requires metabolic precursors and growth factors to grow. These can include vitamins, amino acids, nitrogenous bases, or other molecules that the bacteria cannot synthesize itself. Additionally, bacteria often need an energy source such as organic compounds to provide both energy and carbon for their growth. The physical environment, including temperature, pH, and concentration of atmospheric gases, especially oxygen, is also critical for bacterial growth.
For fastidious bacteria, which have more specific nutritional needs, specialized microbiological media that contain protein extracts, inorganic salts, sometimes carbohydrates, and necessary vitamins or growth factors must be provided. This ensures that these bacteria acquire their required macronutrients, such as carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, as well as micronutrients for enzyme function and growth.
