An animal cannot metabolize nutrients.

Bacteria can metabolize via fermentation. Some bacteria also metabolize via photosynthesis using the sun and inorganic materials, these are known as lithotrophs or autotrophs.
First of all, the human fetus does have oxygen. The oxygen is obtained from the mother's blood via the placenta. But if the fetus did not have oxygen temporarily, s/he could still metabolize glucose. This would be done the same way that other humans metabolize glucose without oxygen--by converting it to lactic acid.
Cyanide blocks your ability to metabolize oxygen inside your cells.
It takes on average 30 to 60 days to metabolize THC from bodily physiology. It takes 6 months however to get beyond detectable levels in hair however, despite how much or how often a person uses.
senior grain for horses provides the nutrients they need without as much fat because their bodies cannot metabolize it as fast.
When cells are given nutrients, they metabolize them, and grow and divide to create more cells. If they are not given nutrients, they die.
Fats
a few bacteria and even then they need to metabolize an element to extract the energy traped in it
granite
Our bodies metabolize food differently.every body is different and everyone needs different nutrients to help with growth.
it can be cycled
Steaming conserves nutrients well because the food's vitamins, minerals and general nutrients cannot be absorbed by water.
proteins
Gum has no nutrients so it cannot be a meal.
They have genetic material surrounded by a protein capsid which can have a membranous layer. Some have reverse transcriptase enzymes. The comparison ends there. Viruses do not metabolize nutrients, do not grow and do not reproduce.
nutrients are used up and then excreted by your body one way or another. Energy is never lost, only transferred, therefore it cannot cycle.
