They have appendix as a working organ, its vestigial in humans.
Ruminants are animals that eat grass. They are specially adapted to digest the cellulose found in grass by having large stomachs filled with fermenting bacteria.
Cellulose in grass can be broken down by ruminant animals such as cows, sheep, and goats that have specialized stomachs with microbes that produce enzymes to digest cellulose. The microbes ferment the cellulose into simpler compounds that the animal can absorb and use for energy. Humans, however, cannot digest cellulose as efficiently due to the lack of these specialized enzymes.
Grass contains primarily cellulose, which is a complex carbohydrate that is difficult for many animals to digest. It also contains smaller amounts of simple sugars like glucose and fructose, as well as other carbohydrates like hemicellulose and pectin.
Ruminants rely on bacteria in their rumen to break down cellulose found in grass into simpler molecules that can be digested by the animals. Without these bacteria, ruminants lack the enzymes necessary to break down cellulose on their own, making grass indigestible for them.
T-rex did not have two stomachs. Today, ruminants (grass eating animals such as cattle) have two stomachs in order to better digest the grass they eat, which is very difficult to digest.
Humans lack the necessary enzymes to break down and digest the cellulose in grass, which makes up the majority of its structure. Additionally, grass does not contain a high enough concentration of protein to sustain human dietary needs. Animals, on the other hand, have evolved to have the necessary enzymes and digestive systems to break down and extract nutrition from grass. Many herbivorous animals, such as cows and sheep, have complex stomachs that allow them to ferment and extract nutrients from grass.
Grass has cellulose, which humans do not have the bacteria to digest, like cows or horses do. You can eat it, but you can't really digest it for energy. Also, something about not having a working appendix.
Rumination is necessary in grass-eating animals because it allows them to efficiently digest tough plant materials, such as cellulose found in grasses. By initially swallowing food without fully chewing it, these animals can later regurgitate the material as "cud" and chew it more thoroughly, which enhances the breakdown of fibrous components. This process maximizes nutrient extraction and supports their energy needs, crucial for their survival in environments where digestible food sources may be limited.
Cellulose is hard to digest plant material found in plants such as grass and leaves.Herbivores such as Cows and giraffes can digest cellulose.certain types of bacteria can digest cellulose as well.
Animals have a circulation that humans don't have
yes. Grass eating animals, or herbivores, are considered to be primary consumers
Herbivores.
