Hi there! I can help you with this!

2. Mesozoic - dinosaurs
3. Paleozoic - fishes & reptiles
4. Precambrian - unicellular organisms
In multicellular organism the energy is stored in the body in the form of <u>Glycogen</u>.
The cells require a constant supply of energy to generate and maintain the biological order that keeps them alive. This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells.
Sugars are particularly important fuel molecules, and they are oxidized in small steps to carbon dioxide (CO2) and water.
Other molecules, such as fatty acids and proteins, can also serve as energy sources when they are funneled through appropriate enzymatic pathways.
