Nutrition

6. = any of a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms.
7. respiration = a type of respiration that does not use oxygen.
9. = any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
10. = a form of malnutrition caused by protein deficiency in the diet, typically affecting young children in the tropics.
12. = the energy needed to raise the temperature of 1 kilogram of water through 1 °C, equal to one thousand small calories and often used to measure the energy value of foods.
13. = the process of providing or obtaining the food necessary for health and growth.

1. = any of a group of organic compounds which are essential for normal growth and nutrition and are required in small quantities in the diet because they cannot be synthesized by the body.
2. diet = a diet consisting of a variety of different types of food and providing adequate amounts of the nutrients necessary for good health.
3. = 1,000 joules, especially as a measure of the energy value of foods.
4. = the process of burning something.
5. = a solid, naturally occurring inorganic substance.
8. = any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body.
11. respiration = the process of producing cellular energy involving oxygen.
