There are many ways in which animals obtain their nutrients. Many of these animals choose to eat or absorb their nutrients.
If they eat grass they would get a lot of nutrients, but because they now eat corn or soy they get few nutrients.
Animals get protein by eating a source of pet food like tuna fish
they eat the herbivores {but i am guessing this is a homework assignment question?}
Humans get Energy and Nutrients from eating Food and by Sleeping.
That's it
Forams have thin pseudopodia that comprise an external net for grabbing food.
it can be obtained by foods.
animals all animals (meats) have protein, some plants have protein too, like peanuts.
Meat and milk and protein
comparing the weight gained in lab animals consuming a test protein with the weight in lab animals consuming a standardized (reference) protein
No
Except for the protein that is used by the animal, protein can be lost in several ways. For example, if the animal has a problem with digestion or absorption, protein can be lost via the faeces. Protein can also be lost into the abdomen, and animals with kidney malfunction can lose protein via urine (eg. a protein losing nephropathy).
Protein is used by the body to build muscles, but is also a food supply for cells. Animals obtain most of their protein by feeding on other animals and plants.
You dont have to ingest animals to receive protein.
Collagen
It's necessary.
All animals need protein because their bodies use the protein to produce energy. Without protein, animals would not be able to create the cellular reactions that sustain life.
Yes, all animals carry protein in their bodies.
