Chapter 34, Problem 1FIB

Summary Introduction

Introduction:

A nutrient is a substance used by an organism for the basic life activities, such as for the survival and reproduction. The requirements for nutrients apply to animals, plants, fungi, and every living organism. Some nutrients can be metabolically converted to smaller molecules during the process of releasing energy, such as for carbohydrates, lipids, and proteins.

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.

Conclusion

Vitamins and minerals are the important nutrients used by the organism for their growth, energy, survival, and reproduction.
