for fermentation, an organism needs a nutrient, like glucose. Using the nutrient, the organism creates energy, without oxygen. In cellular respiration, the organism needs a nutrient and oxygen to create energy.

Fermentation is a form of cellular respiration where yeast uptain energy to live. They digest sugar and produce CO2. Yeast do not need oxygen to do fermentation. In cellular respiration, organisms like humans break down stored energy found in food and glucose. Much of this energy is released in the form of heat (60%) and the rest becomes chemical energy that can be used immeadiately or stored for future use.
