Introduction (परिचय) ( Improvement in Food Resources Class 9 )
Food resources include plants and animals that provide food for humans.
Food resources are improved by increasing production, improving quality, and protecting crops from diseases and pests.
खाद्य संसाधनों में पौधे एवं पशु शामिल हैं जो मनुष्य को भोजन प्रदान करते हैं। खाद्य संसाधनों में सुधार उत्पादन बढ़ाने, गुणवत्ता सुधारने तथा फसलों को रोगों एवं कीटों से बचाने के माध्यम से किया जाता है।
