Answer to Problem 1FIB
Correct answer:
Two general roles for nutrients are to provide energy and raw material. Nutrients required in small amounts that often assist in enzymes function are called vitamins. Nutrients that are elements are called minerals. Nutrients that cannot be synthesized by the body are called essential nutrients.
Explanation of Solution
A nutrient is a substance used by an organism for their survival, growth, and reproduction. Nutrients intake applies to animals, plants, fungi, and protists and every living organism. Those nutrients which cannot be produced by the body and must be present in the diet are called as essential nutrients.
Vitamins are organic compounds that an organism requires in a smaller amount and it is also essential for growth and survival of the living being. Minerals are chemical elements required as essential nutrients by an organism to perform basic functions of life. Most of the minerals in a human diet are taken by eating plants and the plant absorbs their essential minerals from the soil.
Vitamins and minerals are the important nutrients used by the organism for their growth, energy, survival, and reproduction.

Organic molecules required in small quantities. Inorganic molecules required in small quantities.arrow_forwardNutrition plays a vital role in a person's overall health and well-being. Not getting enough of the recommended nutrients over the long term can lead to malnutrition which often results in disease and illness. In a 3-page paper, written in APA format using proper spelling/grammar, address the following: Define malnutrition and identify a specific disease that can result from it. Perform library research about the selected disease and explain its physiological effects on a person's body. Describe the relationship between specific foods/nutrients and the disease. Use the questions below to guide your response. a) Does research indicate that a lack of specific foods/nutrients increase a person's chance of contracting the disease? b) Are there specific foods/nutrients that should be avoided by an individual afflicted with the disease? c) How do specific foods/nutrients work physiologically within the body to help combat the disease?
