Questions & Step-by-Step Solutions
Which of the following is NOT a macronutrient essential for bacterial growth?
Step 1: Understand what macronutrients are. Macronutrients are nutrients that organisms need in large amounts for growth and energy.
Step 2: Identify the common macronutrients essential for bacterial growth. These include carbon, nitrogen, and phosphorus.
Step 3: Recognize what micronutrients are. Micronutrients are nutrients needed in smaller amounts, such as vitamins and minerals.
Step 4: Identify zinc as a micronutrient. It is important for various biological functions but is not needed in large amounts like macronutrients.
Step 5: Conclude that since zinc is a micronutrient and carbon, nitrogen, and phosphorus are macronutrients, zinc is NOT a macronutrient essential for bacterial growth.
