Yes.
Organisms need to carry out the process of respiration because the cells in the organisms break down simple food molecules and release their energy.
All living things are organisms. There is no such thing as a living cell that is not an organism.
If it is alive then it is an oganism. You just need to know if it's alive. Anythin' that is living is an organism. depends on the cell and the level of organization: bacterial cells are considered organisms liver cells are not organisms read up on cell theory (not the marxist kind) that should clarify the definition of organisms for you.
cells
The smallest structure that can carry out all of life processes is the cell. The cells of the body, are what keep the entire body alive.
Anaerobes like archaebacteria and other microorganisms
because every living thing needs to do this to survive
Cells are the basic structural and functional units of living organisms. They provide structure, process nutrients, and carry out essential functions for the organism to survive and function properly. Cells also help organisms grow, reproduce, and respond to their environment.
Cells become specialized through a process called differentiation. During differentiation, cells undergo changes in gene expression, leading to the development of specific structures and functions that enable them to carry out particular roles within the organism. This process is tightly regulated and allows for the diversity of cell types found in multicellular organisms.

Organisms use the oxygen they absorb from the air for their cells. The cells need this oxygen in order to carry out their functions.
