Read the given passage and answer the questions that follow based on the passage and related studied concepts. Intensive farming is an agricultural system that aims to maximize yields from available land through various means, such as heavy use of pesticides and chemical fertilizers. On the other hand, organic farming is a farming system with minimal or no use of chemical fertilizers. Both the farming systems differ in the yield produced, inputs required and effect on soil characteristics like water holding capacity, soil microorganisms, aeration, etc. The graph given below shows the effect of organic manure and chemical fertilizers used in these two types of agriculture systems on the crop yield over a period of time.
