Final answer:
The sacculated stomach with specialized gut bacteria, seen in some animals, is called a multi-chambered stomach. Ruminants, such as cattle or giraffes, have a four-compartment stomach that is colonized by bacteria and protozoa to aid in digestion.
Step-by-step explanation:
The sacculated stomach with specialized gut bacteria, seen in some animals, is called a multi-chambered stomach. One example of an animal with this type of stomach is a ruminant, such as cattle or giraffes. Ruminants have a four-compartment stomach, consisting of the rumen, reticulum, omasum, and abomasum. These chambers are colonized by bacteria and protozoa that help break down cellulose and ferment ingested food. The fermentation process in the stomach produces gas, which needs to be eliminated.
