Cows And Rabbits

Comp be and contrast the ways that cows and rabbits extract ponderousness from diets consisting largely of cellulose; relate this to the structure of each animals digestive tract. (Hint: first you must explain why cellulose is a problem.)  In comparison, both cows and rabbits are herbivores and eat in the first place plants. Plant sell walls are made of cellulose, which are unruffled of glucose monomers that arent useful unless broken strike down into glucose (sugars) to be used for energy. sole(prenominal) if herbivores need something to switching down glucose.  COWS: they have a 4-chambered stomach. - the esophagus is connected to :<span> </span> --1. Rumen: it does microbial digestion --2. Reticulum: in here, food and cellulose is digested by microbes ------ microbes are bacterium/ single celled eukaryotes ------ cows dont have enzymes to break down cellulose, so microbes do it for them ------ huge amounts of saliva create a serious environmen t to help microbes digest the food  ------ the food wherefore goes back up to the esophagus to be chewed again and to reach nutrients available for both cows and microbes --3. Omasum: water re absorption ------ Regurgitated food comes back as cud into reticulum and and then to the Omasum --4. Abomasums: acidic environment where whatever is remain is digested. excess microorganisms are harvested and digested.

 - NUTRIENTS (that they get):  -- Sugars and proteins from unwrap are directly listless -- absorbing microbial digested grass molecules (cellulose --> glucose) --actual microorganisms thems elves (they leak out sugars, oily acids, et! c. to be absorbed by the cow)  RABBITS: - They use CORPROPHAGY: consume feces -- There are commonly parasites in feces, and usually dont provide much nutrition -- Rabbits use corprophagy to break down cellulose into energy so that they can use -- stomach (2 sections)  -- has a large cecum with a bunch of microbes for digestion (similar to the cow) ----- microbes only do digestion AFTER it passes through the...If you want to get a stiff essay, order it on our website: BestEssayCheap.com
