Identify and name the characteristic of life which expressed in Bold

Dear student,
Please find below the answer:

i. Laying eggs by crow is reproduction. Reproduction is a life characteristic. 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. 

ii. Growing taller is growth and development. Growth and development are also considered as life processes as these require energy and take place continuously.

Hope this clears your doubt.
Regards.
