  • The behavior of individual organisms is influenced by internal cues (such as hunger) and by external cues (such as a change in the environment).
  • An organism's behavior patterns are related to the nature of that organism's environment.
  • All organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions in a constantly changing external environment.
  • Regulation of an organism's internal environment involves sensing the internal environment and changing physiological activities to keep conditions within range required to survive.
