Detailed explanation-3: -Life processes are the series of actions, such as movement, respiration, sensitivity, growth, reproduction, excretion and nutrition that are essential for a living being to sustain.

Detailed explanation-4: -The common life processes in plants and animals include-respiration, growth, nutrition, transportation, reproduction and excretion.

Detailed explanation-5: -The matter is digested into raw materials that are used to build structures and repair damaged body parts. The breakdown of also releases energy that can be used for life processes, such as motion to find more things to eat. Animals drink and eat food to obtain the matter and energy they need for their life processes.
