How is the ruminant digestive system different than human digestive system?​
bulgar [2K]

background info:

Digestive system in animals is an important system in the context of digestion of ingested food into simpler forms that could be easily absorbed by the body cells.

This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their habitats.

answer:

Ruminant species survive only on plant matter. They are herbivorous animals.

Therefore, the digestive system of ruminants is evolved with the presence of a rumen which is a complex stomach with four different compartments.

Humans are omnivorous who depend on plant and animal matter both thus, their digestive system composes of one stomach.

This is the key difference between digestion of humans and ruminants.

hope this helped

The formulae of finding the volume of a cone =  1/3 * π * r² * h

(r = radius; h = height)

Therefore replacing the variable with values gives = 1/3 * π * 13² * 27

= 4,778.3624261100755157016805859681‬

Volume to the nearest tenth = 4778.4 cm³
