It takes place in a specific way, this
growth and development is

fixed length of life
Organisms
• Respond to Stimuli - The ability to
respond to stimuli is typical of all living
organisms. Biologists call this property
irritability.

makes that makes it better suited to its
environment is called adaptation.
