How Do Beavers Digest Wood?

·   Beavers’ digestive system is highly specialised to digest cellulose. Cellulose is the main component of wood.

·   Generally, cellulose is not adjustable to every animal.  As it is one of the complex compounds.  And its digestibility rate is very low. As it takes much time to break down.

·     In order to digest the woody parts of the plant, Beavers have different microorganisms in their gut.

·    These microorganisms secrete special enzymes that help in the digestion of cellulose.  Consequently, the breakdown of cellulose compounds becomes very easy.

·     Hence Beavers  munch on wood and  other woody plant parts  without any difficulty  of digestion

 Beaver’s Food Preferences With Seasons

Beavers are very genius semi-aquatic rodents.  They plan their food consumption and food variety according to the availability of food.

 Let us consider an example here, in summers surplus amount of food is available.  The plants are green and their nutritious leaves are the prime choice of food to these animals.  Moreover, there are a massive amount of shrubs and mushrooms.

 Twigs, ferns, branches, and other leafy matter is also abundant.  Hence there is no food shortage, and they can munch on their favourite food in summer.

 On the other hand, the availability of food is not very good in winter.  Mostly in North America as well as in Europe, the winters are very harsh.  And everything is covered with snow so there is no greenery.

 In this situation, the consumption of the inner bark of trees becomes high.  However, sometimes beavers tend to store a good amount of food in the mud in their lodges.  This helped them to eat in their houses without getting out and searching for food.

 We hope now you have got all the answers of your mind regarding the diet of these rodent animals from the Kingdom Animalia.
