Bacteria that grow on the roots of some bean This website is managed with an aim to provide the reader with knowledge-worthy information regarding Zoology and other biological sciences. Mechanical and chemical digestion of food takes place in many steps, beginning in the mouth and ending in the rectum. Some carnivores, particularly cats (family Felidae), are obligate carnivores, meaning they cannot obtain all the nutrients that they need from the plant kingdom and bacteria. Primarily via And, this repeating flow of nitrogen is better known as the nitrogen cycle. Herbivores face a broad range of defences when feeding on plants. Further breakdown of food takes place in the small intestine where enzymes produced by the liver, the small intestine, and the pancreas continue the process of digestion. When humans and animals exhale, they release carbon back into the air by a process called ____________. The solid waste is eliminated through the anus using peristaltic movements of the rectum.
