Which of the given statements is incorrect about the nutritional quality of food crops?
1 Cereals are generally low in protein content.
2 Legumes tend to be low in tryptophan amino acid.
3 Corn, wheat, and rice are low in lysine amino acids.
4 Rice is a rich source of proteins and vitamin A.
Explanation:
Rice has a low content of proteins and completely lacks vitamin A. Cereals such as corn, wheat, rice, millets have a poor lysine content.

Select the option that correctly represents some of the essential micronutrients required by the human body.
1 Iron, nitrogen, oxygen and phosphorus
2 Iron, vitamin A, iodine and zinc
3 Iron, vitamin A, carbon and potassium
4 Manganese, copper, nitrogen and carbon
Explanation:
Essential nutrients are the ones that are not synthesized in the human body and must be taken with food. Iron, vitamin A, iodine and zinc are some of the essential micronutrients as the human body requires them in a trace amount.

Parents often complain about fatigue and weakness in their children despite the proper intake of food. Which of the following could be a reason behind the same?
1 Hidden hunger
2 Over consumption of proteins
3 Obesity
4 Over consumption of carbohydrates
Explanation:
Consumption of balance diet is required so that the body obtains all the required nutrients in the proper proportion. Intake of food deficient in nutrients such as micronutrients, proteins and vitamins causes deficiency symptoms and is called hidden hunger.

Which of the following micronutrients is correctly matched with its respective deficiency disorder?
1 Vitamin A – anemia
2 Iron – night blindness
3 Iodine – goiter
4 Zinc – beriberi
Explanation:
Deficiency of essential nutrients in the diet leads to several disorders. Deficiency of vitamin A, iron and iodine causes night blindness, anemia and goiter, respectively. Deficiency of zinc in food may cause hair loss, diarrhea, chronic kidney disorder, etc.

Application of breeding or biotechnological processes to improve the nutrient levels of crop plants is known as
1 biogeochemistry
2 biofortification
3 biomagnification
4 plant breeding
Explanation:
Many staple crop plants lack essential nutrients and cause hidden hunger and several deficiency disorders. To improve food quality, breeding techniques are applied to crop plants. The improved crop varieties have higher levels of the nutrients which were otherwise absent or were present in a lower amount in them.
