I don't believe there is any "food" that will last forever by itself. However you can preserve food to make it last longer.
One food that has most of the essential nutrients, along with good amounts of proteins, and fatty acids is milk. While cow's milk would suffice, goat's milk has been purported to hold more nutritional value.
So technically you could combine the two together and have preserved milk, which is a whitish powder of dried milk (powdered milk), often used in baby foods and is commercially sold. Milk powders contain all twenty standard amino acids and are high in soluble minerals and vitamins. As an added bonus, companies often fortify the milk powder with vitamins A and D. Unfortunately powdered milk cannot last forever, although it has a very long shelf life.
essential nutrients
Your food which contains the nutrients goes through your digestive system. This should take all essential nutrients out. It is not likely there would be any nutrients left in your body but if there was you would descrete them (they would come out in your poo)
Carbon, Hydrogen, Oxygen, Nitrogen, and sometines Sulphur and phosphprus make up the majority of biochemical compounds. These are essential. This does not include minerals or metals such as iron used by hemes for oxygen transportation
The essential things a human needs to stay alive are water, food and oxygen.
Autotrophs don't necessarily "make" anything that heterotrophs need. The word autotroph means that the organism produces its own source of food. Heterotrophs depend on autotrophs as an essential source of food and nutrients (nitrogen, etc.).
protein (sperm)
No, lentils are another excellent source of a single food that contains all the essential nutrients for survival.
Digestive system
Food is what gives the body the essential nutrients it needs. The food itself does not make you grow, the nutrients are what is used by the body to power its growth.
the ingredients to provide nutrience are food
true
They help you swallow and digest food... If you didn't digest food, you can't get the nutrients that are vital to life
It is required to supply chemical energy, organic molecules, and essential nutrients
essential nutrients
Animals must digest food to receive the essential nutrients that the particular organism needs to survive.

No. In a female, the placenta provides the nutrients and essential counterparts to support the growing fetus.
