Food is necessary for both living organisms, and technical devices. Certainly, it is organized at the first and second absolutely differently. The general is only one: thanks to food both that and others receive energy.
Instruction
1. Living organisms eat products which contain not only energy carriers, but also the substances which are some kind of construction materials. They are divided into three big groups: proteins, fats, carbohydrates. In addition, vitamins and mineral substances are necessary for a living organism also in small amounts.
2. The growing organism thanks to food gradually increases in sizes. After the same as the period of growth comes to the end, a part of nutritive matters is spent for obtaining energy, and other part - for regeneration of fabrics.
3. Food has to be balanced. All nutritive matters have to come to an organism in certain quantities and also in certain proportions between these quantities. Otherwise a number of diseases, including obesity can develop. Sometimes it is necessary to keep to a diet, excepting any given of products. Food have to be good-quality in order to avoid poisoning.
4. Animal food differs from vegetable in bigger concentration of energy. But abuse of it harms an organism. In some diets it is cancelled in whole or in part, but it is also useful not for all.
5. Technical devices need food only for obtaining energy. In the course of work they don't grow, and regeneration of any components in them also doesn't happen. If any of details wears out, it is just replaced, but it isn't connected with food in any way. However, also exceptions of this rule meet, for example, at use of additives to fuel which are capable to prevent wear of some details of the engine and to restore them.
6. Power supply of technical devices also has to be good-quality. If it is about the electric power, tension has to be rather stable, without failures, splashes and hindrances and if about fuel, then in it it is necessary to exclude presence of a number of impurity, pernicious for the engine.
