becauseeven food that we eat are foreign bodies, that is why some phago cyte attack them. correct me if im wrong..
The correct answer for this is,the food particle is an antigen to our body but our body accepts it because, as we intake our food first the digestive enzymes act upon the food then they are digested into simple substances i.e carbohydrates,proties and fats which inturn are composed of carbon,hydrogen,nitrogen....our DNA is composed of these compounds if u see the backbone and structure of DNA it is composed of carbon rings nitrogenous compounds and hydrogen bonds so as our DNA is composed of these substances the body accepts the food particles....Carefully.
The amoeba moves its psuedopodia (false feet) around the food particle. thus a food vacuole is formed.then the amoeba secretes digestive enzymes into the food vacuole and the food particle is digested and assimilated.the waste particle is thrown out by moving the particle towards the surface of the body and it is excreted. :)
its food
Human body is not making food. only plants making food.
The human body converts food energy into work, thermal energy or chemical energy that is stored in fatty tissue.

An Antigen is considered as any foreign particle that enters the body such as dust, food and any microorganisms. An Immunogen is any foreign particle that triggers an response from the body's immune system. Consequently, all Immunogens are Antigens, but not all Antigens are Immunogens. To be considered an Immunogen, the particle has to have all the following characteristics: 1- Has enough atomic mass to be recognized by T cells and Antigen Presenting cells 2- Be significantly different from all of our cells or metabolites. 3- Must have a defined secondary and tertiary structure (has to be firm to form an epitope) 4- Has to be an antigen eg: Carbohydrates are not a highly immunogenic antigen, since they are made of glucose which is essential for our body's metabolism. Moreover, our body has the ability to store glucose as glycogen. An Adjuvant is a compound that increases the immunogenicy of antigens when mixed together.
In the human body there is no "opening" that stores food.
active transportAmoeba gets the food through the process of endocytosis.it can engulf the food particle from every side of its body(cell) surface by making psuedopodia when it comes in contact with the food particle.
The food is ingested in the form of large, complex and inabsorbable particle wich is changed into fine, simpler, absorbable forms. This process is known as digestive glands.
For energy
they well be fat:P
Carefully.
Food
Food and water

because while refreezing some bacteria and virus will be getting inside the food particle which will affect our body.
