Question

The small intestine of a lion is shorter in length
than that of a deer.
give the scientific reason:
​

Answer 1

Answer:

Length of digestive tract

Length of digestive tract

The morphology of mammals’ digestive tracts reflects their evolutionary adaption to different diets (Fig. 1). The digestive tract of herbivorous mammals is generally much longer than that of carnivores [1]. The increased length – especially of the small intestine – allows for more time for the cellulose of plant cell walls to be broken down by microorganisms.

Digestive systems of various mammals with different diets. Note how much longer the digestive tracts (especially the small intestine) of herbivores are compared to that of carnivores

The human digestive tract

Fig. 2: The human digestive tract. Its length is around seven times that of the body length [2].

Table 1 gives some examples of digestive tract length as a percentage of body length (distance from mouth to anus).

Answer 2

Answer:

true because deer is herbivores
