Answer in detail.
How all the life processes contribute to the growth and development of the body?
Answer:
The processes which maintain body functions and are necessary for survival of the living organisms are called life processes. The important life processes are nutrition, transportation, metabolism, reproduction, respiration, and excretion. Nutrition provides food, respiration provides energy, excretion is the removal of waste from the body, metabolism is the sum of chemical reactions and reproduction is the process through which organism produces offspring. All the organ systems of the body are performing their functions independently but through a complete co-ordination. This overall system is in action in more or less same way in all the organisms. Therefore, all the life processes together bring about growth and development of the body.
