Class 9 Biology Improvement Food Resources Introduction


Any edible substance of plant or animal origin that provides nutritional benefits such as carbohydrates, fats, proteins, vitamins, or minerals to an organism when consumed is called Food.

A meal that includes adequate amount of proteins, carbohydrates, fats, vitamins and minerals is called Balanced diet. A balanced diet should contain pulses, fruits, vegetables, milk, iron-rich food, and other nutrient rich food in requisite proportions.


The reasons for need of improvement of food production:

  • Meet the needs of growing population: The food items are grown in fields by the farmers. The demand of food is increasing with increasing population. Therefore it is necessary that the yield of crop also increases.
  • Less scope of increasing the area of land under cultivation : Not all the lands around us are available for agricultural purposes. Many of them are used for residential purposes, building schools, colleges, hospitals, shopping malls and many uses other than agriculture. Therefore we need to increase the crop production using modern technologies and techniques. But at the same time we should take care that there should not be any harm to the environment.
  • People are suffering from malnutrition: Producing more and more crops will not solve the problem of malnutrition. The produced crops should be accessible to all. Therefore, along with increased crop production there should be good economic conditions to ensure affordability.
