Answers
All living organisms need food because:
1) It provides carbohydrates, fats vitamins and minerals
2) It allows development of the organisms
3) It is needed to gain energy for everyday tasks
Main sources of food:
1) Plants – obtained from agriculture
2) Animals – obtained from animal husbandry
The efficiency of crops and livestock is required in India because:
The population of India is growing at a faster rate hence more amount of food is required to meet the rising demand.
The agricultural land is limited as compared to the growing population.
Efforts made to meet the increase in food demands
Green Revolution – The introduction of modern technology and equipment, usage of fertilizers and high-quality seeds
White Revolution – Increasing the growth of milk production by introducing dairy development programs
The introduction of these revolutions has led to an increased use of natural resources hence now sustainable methods of increasing crops and livestock efficiency are also required.
