Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.
