<u>Answer:</u>
<em>The purpose of genetically modified crops is increasing the food supply. </em>
<u>Explanation:</u>
<em>When crops are attacked by pests the yield of the crops reduces.</em> The natural pest tackling adaptations of the plant is not just enough to check the invasion of crops by pests. Introducing feature of pest resistance into the <em>genes of plant species will make them pest resistant.</em>
Genetic modification is the method used to achieve this objective. In genetic modification a previously absent feature is introduced into a plant species by various scientific techniques.<em> This feature can be pest resistance, chemical resistance, improved nutrient profile etc. </em>
