Living things need energy to carry out their life processes. Animals get this energy from food through a process called cellular . The first stage, glycolysis, occurs in conditions, or without oxygen. The second stage, called the Krebs cycle, and the third stage, electron transport, require the presence of oxygen, and are therefore
