animals all animals (meats) have protein, some plants have protein too, like peanuts.
Yes, all animals carry protein in their bodies.
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.
All animals need protein, and amino acids are the building blocks of protein.

As the plant have to use the protein to build up cytoplasm , amino acid .......

Pretty much all animals, but particularly mammals. There are different types of proteins, though, so you have to be more specific if you're after specific ones.
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).
Cologyn is another way of spelling collagen, which is the protein that makes up the connective tissue in animals. It makes up about 25% of all of the protein that an animal contains.
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.
