Document Summary
Autotrophs are the source of all organic material for the heterotrophs. Two different kinds of heterotrophs based upon where material is digested. Extracellular digestion, most advanced animals take this. there"s a gut . Indirectly from plants via another animal (carnivores and parasites) From a combination of plants and animals (omnivores) A source of carb, glycerol, fatty acids, lipids, animo acids, proteins, nucleotides, and nucleic acids. All of these have a carbon skeleton which obtained by eating carbohydrates, lipids, and proteins, Macromolecules are digested into component subunits before entering cells. Many animals can synthesize only some of the amino acids and must get the rest through diet. Leucine, isoleucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Human body can synthesize all necessary lipids and fatty acids except for cholesterol and unsaturated fatty acids needed for membranes. Sulfur is needed for animo acids formation. Iron is needed for pigmentation and hemoglobin. Mineral enzymes co-factors magnesium, zinc, manganese, and cobalt.
