No, it is a cell.
No, it is not an organism. It is a component of an organism, which is an animal.
yes
No, they are a working part to make an organism work correctly.
I don't think there are actually any organisms living in a red blood cell.
The lungs take oxygen into the body and the blood transports oxygen throughout the body.
The process by which a white blood cell ingests a disease-causing organism is called phagocytosis. The white blood cell engulfs the pathogen using its cell membrane, forming a vesicle called a phagosome. The phagosome then fuses with a lysosome to form a phagolysosome, where the pathogen is destroyed.
Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell and the vertebrate organism's principal means of delivering oxygen.
A white blood cell is not an organism because it cannot live separately from the rest of the cells making up a human being. It is, however, similar to single-celled organisms like amoebae.
The organism you are referring to is a prokaryotic cell. Prokaryotic cells lack a nucleus and other membrane-bound organelles. They are typically found in bacteria and archaea.

The answer is to search it up not ask just anyone!
