6. 5. Living organisms consume and transform energy

7. Characteristics of Life 1.Homeostasis: regulation of the internal environment to maintain a constant state 2.Organization: being structurally composed of one or more cells

8. 3. Metabolism: transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (Catabolism)

10. 5. Adaptation: Ability to change over time in response to the environment

11. 6. Response to Stimuli
