Editing Behavior (section)

==== Definition ====
Behavior may be defined as "the internally coordinated responses (actions or inactions) of whole living organisms (individuals or groups) to internal or external stimuli".<ref>{{cite journal|last=Levitis|first=Daniel |author2=William Z.

A broader definition of behavior, applicable to plants and other organisms, is similar to the concept of [[phenotypic plasticity]]. It describes behavior as a response to an event or environment change during the course of the lifetime of an individual, differing from other physiological or biochemical changes that occur more rapidly, and excluding changes that are a result of development ([[ontogeny]]).<ref>Karban, R.

Behaviour can be regarded as any action of an organism that changes its relationship to its environment. Behavior provides outputs from the organism to the environment.<ref>Dusenbery, David B.
