Answer:
(a)
Food is necessary for the growth and development of the body. Balanced diet
provides raw materials and energy in appropriate amount needed through
nutrients like proteins, carbohydrates, fats, minerals, etc. which in turn are
essential for the proper growth and functioning of a healthy body.
(b) Health is a state of being well enough to function physically,
mentally and socially well and these conditions in turn depend upon the
surrounding environmental conditions, e.g., if there are unhygienic conditions
in surrounding area, it is likely that we might get infected or diseased.
(c) This is so because many water-borne diseases and
insect vectors flourish in stagnant water which cause diseases in human beings.
(d) Human beings live in societies and different
localities like villages or cities, which determine the social and physical
environment and hence both are to be kept in harmony. Public cleanliness is
important for individual health.
For better living conditions money is required. We need
good food for healthy body and for this we have to earn. For the treatment of
diseases also, one has to be in good economic condition.
