BIOL 1107 Chapter Notes - Chapter 47: Nutrient, Organic Compound, Overnutrition
Document Summary
Plants only need sunlight and inorganic precursors (h 2 o, co 2 , minerals) to make all organic molecules. Animals require constant diet of organic molecules for energy and nutrients. Herbivore : animal that obtains energy and nutrients primarily by eating plants. Carnivore : animal that primarily eats other animals. Omnivore : animal that feeds at several trophic levels, consuming plants, animals, and other sources of. Act as fuels for oxidative reactions that supply energy. Are the building blocks for making complex biological molecules. Energy in fuels is measured in calories. In animal nutrition, food energy is presented as kilocalories. Carbohydrates, proteins, fats are 3 main types of energy-rich food consumed by animals. Fats provide 2x calories per gram as the carbs and proteins. Malnutrition : condition resulting from a diet in which intake of organic fuels is inadequate or whose assimilation of such fuels is abnormal or excessive.
