Respiration is the intake of oxygen to continue living. We breathe, natural respiration. We are assisted in breathing, artificial respiration. When we are dead, lack of respiration, decomposition takes place.

Here’s a song about cellular respiration.
Glycolysis:
There are two important ways a cell can harvest energy from food: fermentation and cellular respiration. Both start with the same first step: the process of glycolysis which is the breakdown or splitting of glucose (6 carbons) into two 3-carbon molecules called pyruvic acid. The energy from other sugars, such as fructose, is also harvested using this process. Glycolysis is probably the oldest known way of producing ATP. There is evidence that the process of glycolysis predates the existence of O2 in the Earth’s atmosphere and organelles in cells:
Glycolysis does not need oxygen as part of any of its chemical reactions. It serves as a first step in a variety of both aerobic and anaerobic energy-harvesting reactions.
Glycolysis happens in the cytoplasm of cells, not in some specialized organelle.
Glycolysis is the one metabolic pathway found in all living organisms .

What is there to justify? All life depends on some kind of respiration. So I guess that's your answer.

Respiration brings in what oranisms need and takes out what the waste products created internally.

I can justify this very well.
Hold your breath for about 10 minutes and if your still alive, you can tell your teacher she got it wrong. But trust me, she wont be standing there for very long since you be the living dead.
