Document Summary

Fluid feeders suck nutrient-rich fluids from a living host. Filter feeders sift small organisms or food particles from water. Animals obtain and ingest their food in different ways. Substrate feeders live in or on their food source and eat their way through it. Bulk feeders ingest large pieces of food. 1: digestion is the breaking down of food into molecules small enough for the body to. Ingestion is the act of eating absorb digestive tract: absorption is the take-up of the products of digestion, usually by the cells lining the, elimination is the removal of undigested materials from the digestive tract. Chemical digestion is necessary because animals cannot directly use the proteins, carbohydrates, fats and nucleic acids in food. Although all organisms use the same building blocks to make their macromolecules, food is disassembled into the individual building blocks, which are then reassembled into the body"s own molecules (a protein, for example) Sponges and protists digest food in vacuoles.
