Which of the following is a macronutrient?
Which of the following is a macronutrient?
- calcium
- chlorine
- zinc
- manganese
The Correct Option is A
Solution and Explanation
Calcium is a macronutrient. Nutrients are the chemical substances required by our body for performing vital functions. Some of these nutrients are required in small amounts while some are needed in larger amounts. Depending upon this, the essential nutrients required by the body are categorized into two types:
- Macronutrients - The nutrients which are required by the body in larger amounts are termed as macronutrients. For example, proteins, calcium, fats etc.
- Micronutrients - The nutrients required by the body in small amounts but are essential, are called as micronutrients. For example, vitamins, minerals etc.
Macronutrients mainly serves to provide energy while micronutrients prevents deficiency diseases like night-blindness, scurvy etc.

Essential Mineral Elements
Mineral Elements:
A large number of inorganic elements are necessary for all the life processes and hence should be taken into our diets in adequate amounts. Any deficiency in these minerals leads to an abnormality in the metabolic functioning of the body.
Essential Mineral Elements in Plants
There are two types of minerals that are essential for plant growth, such as:
1. Macrominerals
Minerals like Phosphorous, carbon, silicon, magnesium, hydrogen, sodium, nitrogen, potassium, calcium, oxygen, selenium, and sulfur are required in abundance for proper plant growth and are also found abundantly in plant tissues. Hence, they are known as macrominerals.
2. Microminerals
A few minerals like Iron, boron, zinc, cobalt, chlorine, nickel, manganese, copper, molybdenum, etc. are required in lesser quantities for proper growth by the plants and therefore, they are called microminerals. Further they are also called trace elements.
