Which term describes nutrients required in relatively large amounts by many organisms?
Correct Answer:
Macronutrients
Explanation:
In nutrition, nutrients are grouped by how much organisms need. Macronutrients are the ones required in relatively large amounts to build tissues, provide energy, and keep body functions running. This category includes substances like carbohydrates, proteins, fats, and several minerals that are needed in bigger quantities. Because the question asks for the term describing nutrients needed in relatively large amounts by many organisms, macronutrients is the best fit. The other options describe different ideas: micronutrients and vitamins are needed in much smaller amounts, with vitamins being a subset of micronutrients. Carbohydrates are a type of macronutrient, but they’re just one example, not the general term for nutrients required in large amounts.
