$<body bgcolor=black> Even when we are not doing any apparent activity, energy is needed to maintain a state of order in our body. We also need materials from outside in order to grow, develop, synthesise protein and other substances needed in the body. This source of energy and materials is the food we eat.$

$ Class 10 Science “Life Processes”All living entities require energy to sustain and maintain life. Plants and animals slightly differ in their raw material intake for survival.The raw materials required by an organism will vary depending on the complexity of the organism and its environment. All animals take in food, water and oxygen as raw material from the outsideAs for plants, they take in carbon dioxide, water and sunlight to synthesize their own food in the presence of chlorophyll(found in green plants). $
