For instance, if we take living things, every time they search for foods to have fuel from it. Why ?they have many tasks to accomplish or they need to simply continue their life cycle. When we come to non-living things like machines, they need fuel to do certain tasks which are ordered by instructor. The nature of each fuel for each thing is different. Some fuels are in a liqued form, solid form, gas form or for other things, sun light is energy source to them. For some machines, electric current is source of energy so that they can function well.
