3. Development can be seen as a product of interaction of the organism or individual and environment.
 

Reproduction is a life process. It is not as such the essential life process for the survival of a living organism but it is a life process necessary for continuity of life. 

Growth and development is also considered as life process as these require energy and taking place continuously.
