Energy > Energy in chemical reactions > Energy in organisms
All living organisms require energy to survive. Organisms transform different types of energy into chemical energy, which their cells use to perform all the necessary functions for the survival of the organism.
Connection to Big Idea about evolution: Part of evolution also involves the refinement of the mechanisms through which living organisms use energy to survive.
Connection to Big Idea about the cell: During aerobic respiration, energy is produced and carried by glucose and adenosine triphosphate (ATP) molecules.
Connection to Big Idea about Earth: All living organisms on Earth depend on the Sun and on Earth supplies (living and no-living) to consume the energy they need to survive. The entire food chain is based on that concept.
