Your a nerd
Which bacteria? You need to be more specific.
Methanogenic archaea are the bacteria that can utilize methane as their source of energy and do not require oxygen for survival. These bacteria produce methane as a byproduct of their metabolism. They play a crucial role in anaerobic environments such as wetlands and the digestive systems of animals.
The animals need the bacteria to help break down the food. The bacteria benefit since they get food, while we benefit since the bacteria help us digest our food.
These bacteria help in digestion and in destroying harmful organisms. Intestinal bacteria also produce some vitamins needed by the body.
It is just a tube to allow the food bits to get into the stomach. Food doesn't need to be digested in this part of the digestive system.
It depends on what kind of bacteria you're talking about. Many bacteria in our own bodies are useful and helpful - for example, the bacteria in our digestive system that takes food and converts it in to the elements we need to survive. Other bacteria can be deadly, such a staph bacteria that cause infections. Bottom line is that not all bactiera are harmful.
Because new gas is produced as a part of a cycle.
The type of interaction you have here is called a symbiotic relationship. This is because neither organism can live with out the other. The cow must have the bacteria to complete fermentation in its rumen to digest cellulose and the bacteria need the cows digestive system because that's the environment necessary for them to thrive. This mutual need is called symbiosis, which is the basis of the term symbiotic.
In addition to killing bad bacteria, antibiotics also kill off bacteria you need, like the bacteria in your digestive tract. Yogurt will help replace some of these bacteria, and may also help you from getting diarrhea while on the pills.
No, not all living things need a digestive system. For example, some simple organisms like bacteria absorb nutrients directly through their cell membrane. However, for complex multicellular organisms, a digestive system is necessary to break down food into nutrients that can be absorbed and utilized by the body.
Herbivores produce less pepsin because their diets are primarily composed of plant material, which is high in cellulose and requires different digestive enzymes for breakdown. Unlike carnivores, which rely on pepsin to digest proteins from meat, herbivores have evolved specialized digestive systems, including longer intestines and microbial fermentation, to efficiently process plant fibers. Consequently, the need for pepsin is reduced, as their digestion relies more on cellulose-digesting enzymes produced by gut bacteria.
yogurt, cheese, beer, and i need 2 more also. i hope my answer helps
