Food and its components
Class 6 Science · Nutrition · 31 questions with answers
This chapter looks like Class 5 EVS and is marked quite differently: the deficiency questions want the nutrient, the disease and the symptom, and dropping any one of the three costs the mark.
- Names the main nutrients and what each does for the body
- Links a deficiency to its disease and its symptom
- Explains why a diet is or is not balanced

Here’s one done for you
rice → carbohydrates. 'Mainly' matters - most foods contain several nutrients, and the question asks which one dominates. Milk is the useful exception on this list, since it is genuinely rich in more than one, and a good answer says so.
- 1)rice
- 2)eggs
- 3)butter
- 4)orange
- 5)milk
- 6)spinach
- 7)groundnuts

Scurvy → vitamin C missing, and the symptom is bleeding gums. Three parts: what is missing, what it is called, what you would notice. Children commonly give two and lose the third mark, so writing all three in one line as a habit is worth more than knowing extra diseases.
- 1)Scurvy
- 2)Rickets
- 3)Anaemia
- 4)Goitre
- 5)Night blindness
- 6)Beriberi
- 7)Kwashiorkor
- 8)Marasmus
- 9)Bleeding under the skin from vitamin deficiency
- 10)Weak, brittle bones in an adult
- 11)Constipation from a diet with no roughage
Answers
- 1) Vitamin C - scurvy - bleeding gums and slow healing of wounds.
- 2) Vitamin D or calcium - rickets - weak and bent bones.
- 3) Iron - anaemia - weakness and tiredness, and pale skin.
- 4) Iodine - goitre - swelling of the neck.
- 5) Vitamin A - night blindness - difficulty seeing in dim light.
- 6) Vitamin B1 - beriberi - weak muscles and very little energy.
- 7) Protein - kwashiorkor - swelling of the face and body, and stunted growth.
- 8) Protein and carbohydrate together - marasmus - extreme thinness and wasted muscles.
- 9) Vitamin C - scurvy - bleeding under the skin and swollen, painful joints.
- 10) Calcium and vitamin D - the bones weaken and break easily.
- 11) Roughage - the food does not move easily through the intestine.

Is this meal balanced? Say what is missing or in excess, and why.

Here’s one done for you
Rice, chapati and potato curry → not balanced, because all three are mainly carbohydrate. The answer has to name what is missing rather than just say 'not balanced'. A useful check for your child: go through the nutrient list and tick off which ones the meal actually supplies.
- 1)Rice, chapati and potato curry
- 2)Rice, dal, vegetables and curd
- 3)Only fruit juice for a whole day
- 4)Chapati, dal, palak sabzi and a glass of milk
- 5)Two samosas and a soft drink
- 6)Idli with sambar and coconut chutney
- 7)Boiled eggs and butter only
- 8)Rice, fish curry, vegetables and curd
Answers
- 1) Not balanced - it is nearly all carbohydrate, with very little protein and few vitamins or minerals from vegetables.
- 2) Balanced - the rice and chapati give carbohydrate, the dal and curd give protein, and the vegetables give vitamins and minerals.
- 3) Not balanced - it provides some vitamins and sugar but almost no protein, fat or roughage, so the body cannot grow or repair itself.
- 4) Balanced - the chapati gives carbohydrate, the dal and milk give protein and calcium, and the palak gives iron and vitamins.
- 5) Not balanced - it is mostly fat, refined carbohydrate and sugar, with almost no protein, vitamins or roughage.
- 6) Nearly balanced - the idli gives carbohydrate and the sambar gives protein and vegetables. Adding curd or a vegetable would improve the vitamins.
- 7) Not balanced - it is protein and fat with no carbohydrate for energy, and no vitamins, minerals or roughage.
- 8) Balanced - rice gives carbohydrate, fish and curd give protein, and the vegetables give vitamins, minerals and roughage.
While your child works
- Deficiency answers need three parts. Writing them as one line - nutrient, disease, symptom - makes the missing part obvious.
- For the balanced diet questions, tick off the nutrients one at a time. 'Not balanced' on its own is never the full answer.
- This chapter overlaps with Class 5 EVS, so it can feel easy. The marking is stricter, which is exactly where marks quietly go.
