See hierarchy chart. Each level of biological organization has emergent properties. With each step upward in the biological hierarchy, new properties emerge that were not present at the simpler organizational levels. Organisms are highly ordered, and other characteristics of life emerge from this complex organization. Growth and Development.
Heritable programs stored in DNA direct the species-specific pattern of growth and development.
Organisms take in and transform energy to do work, including the maintenance of their ordered state. Response to Environment. Organisms respond to stimuli from their environment. Organisms regulate their internal environment to maintain a steady-state, even in the face of a fluctuating external environment. Life evolves in response to interactions between organisms and their environment.
