Digestion allows the foods that we eat to be broken down into the nutrients that our body needs to function: simple carbohydrates, essential amino acids, fatty acids (glycerols), and essential minerals. Most carbohydrates that we eat are complex carbohydrates that our body cannot use unless they are broken down. Digestion is the process that breaks down such complex carbs into simple carbs useful to our body. We eat proteins but amino acids are the building blocks for such proteins, and amino acids are essential for the functioning of our body. Digestion breaks down the protein into amino acids that our body can use.
The digestive system is necessary because you need to digest the food and get the energy (and other things your body craves) from the food you eat. Your body needs to break the food down and either use or store the materials.
Digestion is necessary because as human beings we must break down our food and metabolize it so we can obtain energy which helps us perform all of our other functions as human beings.
The gastrointestinal tract uses both chemical and mechanical digestion.
The digestive system is related to the nervous system in such a way that the nervous system dictates the speed of breaking down of food. The nervous system overseas activity in the digestive tract, and regulates secretion if there are changes.
Salivary gland is the external digestive gland associated with digestive system of humans.
The first task of the digestive system is to break down food into a fine pulp (mechanical digestion). When the food is physically broken down, digestive chemicals break the food down into small molecules (chemical digestion). The mouth is the organ in which the process of digestion begins.(Google)

Why is it necessary for food to digested
yes

Blood has to be pumped to the digestive system so that carbon dioxide can be extracted from it. The blood can also absorb nutrients that have just been collected from the digestive system.
Tapeworms feed on already digested food as they live in the gut (stomach). Therefore a digestive system isn't necessary.

Well, it the word THE is a sentient being and needs to eat, then it will need a digestive tract to break down food and distribute its nutrients to the body.
Kernel corn is not digested, it is a food that most people eat whole. This is due to lack of the necessary digestive enzymes.
The smooth muscles in the intestines push the materials through itself and the digestive system provides the necessary protein and energy the muscle system needs.
The gastrointestinal tract uses both chemical and mechanical digestion.
Bacteria in the digestive system are necessary for digestion and the production of vitamin K in the colon. Viruses rarely even make it to the stomach; they infect by reaching the bloodstream.
Protein is a necessary element that allows for normal absorption of iron by the digestive tract. Without protein to bind iron molecules together the iron can become toxic and form into free radicals that can poison and damage the body.
