Cows And Rabbits

Comp be and contrast the ways that cows and rabbits extract heftiness 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 general plants. Plant sell walls are made of cellulose, which are quiet of glucose monomers that arent useful unless broken put through into glucose (sugars) to be used for energy. only(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 alter environment to help microbe s digest the food  ------ the food consequently goes back up to the esophagus to be chewed again and to gain nutrients available for both cows and microbes --3. Omasum: water re absorption ------ Regurgitated food comes back as cud into second stomach and and then to the Omasum --4. Abomasums: acidic environment where whatever is rest is digested. excess microorganisms are harvested and digested.

 - NUTRIENTS (that they get):  -- Sugars and proteins from unwrap are directly command -- absorbing microbial digested grass molecules (cellulose --> glucose) --actual microorganisms themselves (they leak out sugars, butterba ll acids, etc. to be absorbed by the cow) Â!  RABBITS: - They use CORPROPHAGY: consume feces -- There are unremarkably 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 laden essay, order it on our website: BestEssayCheap.com
