Solution

a) Food is essential for the growth and normal functioning of our body. A balanced diet is the one which consists of all the essential nutrients in an appropriate quantity. A balanced diet provides an appropriate amount of biomolecules such as carbohydrates, lipids, proteins, vitamins and minerals which are very essential for our growth and body functioning. Imbalance in the diet leads to many physical and physiological disorders.

b) Health is defined as physical, mental and social well-being and comfort. Health is always dependent on our surroundings and if our environment is unhygienic we get a disease. We get cold and cough in rainy and winter season. Our environmental conditions are very important for being healthy.

c) Stagnant water is the breeding ground for mosquitos. Mosquitos spread many diseases like Malaria, Dengue, Elephantiasis, chikungunya etc. In order to stop the spread of these diseases, our surroundings should be free of stagnant water.

We need hygienic food to lead a healthy life which depends on our economic conditions.
