The solid waste is eliminated through the anus using peristaltic movements of the rectum. Carnivorous animals obtain their needed nitrogen from protein in the meat they eat while herbivorous animals obtain nitrogen through plant materials that has a high protein or amino acid content such as leguminous plants. Now utilize the next two management steps, listed below, as you work on your project. The fermentation process produces large amounts of gas in the stomach chamber, which must be eliminated. Bacteria change nitrates in the soil into nitrogen gas. The salivary enzyme amylase begins the breakdown of food starches into maltose, a disaccharide. This includes an understanding of the cycling of matter and flow of energy in living systems. Recall that the chyme from the stomach enters the duodenum and mixes with the digestive secretion from the pancreas, liver, and gallbladder. The food particles are engulfed by the cells lining the gastrovascular cavity. are all made up of nitrogen. How is nitrogen returned to the atmosphere? Most of the chemical digestion and absorption happens in the intestine and the waste is excreted through the cloaca.

Platyhelminthes (flatworms), Ctenophora (comb jellies), and Cnidaria (coral, jelly fish, and sea anemones) use this type of digestion. Food needs to be broken into smaller particles so that animals can harness the nutrients and organic molecules. Actually, when there is no available oxygen, denitrifying bacteria use the oxygen present in the nitrate to oxidize the carbon. When chyme enters the duodenum, the hormonal responses trigger the release of bile, which is produced in the liver and stored in the gallbladder.
