Document Summary
Nutrition: how an animal takes in food (ingestion), breaks it down (digestion), and gets necessary materials from it (absorption) Plants photosynthesize, created organic molecules from water, sunlight, and inorganic molecules. Omnivores: eat whatever organic matter their enzymes can digest (plants and animals) Fueling oxidation reactions that provide energy for metabolism, growth, homeostasis, and reproduction. Supply units to build complex biomolecules: carbohydrates, lipid, nucleic acids, and proteins. Three main components that supply energy: carbohydrates, proteins, fats. Essential nutrients: cannot be synthesized, must be consumed essential amino acids essential fatty acids. Vitamins: organic molecules that need to be eaten in small amounts, can be coenzymes. Minerals: inorganic molecules required in small amounts in diet. Fluid feeders: drink liquids (blood, nectar) with organic molecules dissolved in them. Adaptation examples: mouthparts for extraction, enzymes to liquify. Suspension feeders: filter out organisms floating in water. Deposit feeders: eat organic material from surface they live in or on (dirt, rocks)
