1 Writing Assignment – Lesson 2 1. A diet is the total composition of the daily intake required for healthy functioning of an organism, whereas a ration is how much of something an organism should take in on a daily basis, as a part of its diet. Essentially, a diet is comprised of rations of essential nutrients. 2. Plants and animals differ in their nutritional needs in that plants only require mineral elements and Nitrogen, obtained from the soil. Animals, however, require more complex nutrients (as well as Nitrogen) such as amino acids, fatty acids, mineral elements, fat and water-soluble vitamins and a source of energy (fat, protein, and/or fibrous plant tissue). Also, plants synthesize all of the complex biochemicals it needs for itself whereas animals require ready-made nutrients from outside sources. 3. 1. (Most important) Any nutrient can be toxic when ingested in excessive amounts, including water. 2. Not all components provide usable nutrients and some may be toxic under certain

Unformatted text preview: conditions 3. Vital organic compounds include N-containing compounds, lipids, carbohydrates, and vitamins. 4. Lipids required by animals are fatty acids, lionleic and linolenic acids, and the fat-soluble vitamins A, D, E, and K. 5. Carbohydrates make up the major fraction of plant tissues but do not make up more than 1% of animal tissues. Glucose is the essential monosaccharide required by all animal cells as an energy source. 4. Composition of the animal body is primarily affected by domestic v. wild status, then age, and then species. 5. Young, growing poultry require three more amino acids than most animals, which are glycine, serine, and proline. 6. In poultry, glycine and serine are considered metabolically interconvertable. That is, the animal’s metabolism is able to convert one into the other and visa versa, so the nutritional requirement is satisfied by either one, or both together....
