All the organisms perform some basic functions to keep themselves alive. The basic functions performed by living organisms to maintain their life on this earth are called life processes.
The basic life processes common to all the living organisms are: Nutrition and Respiration; Transport and Excretion; Control and Coordination (Response to stimuli); Growth; Movement and Reproduction. The process of nutrition involves the taking of food inside the body and converting it into smaller molecules which can be absorbed by the body.
Respiration is the process which releases energy from the food absorbed by the body. Transport is the process in which a substance absorbed or made in one part of the body is moved to other parts of the body. Excretion is the process in which the waste materials produced in the cells of the body are removed from the body.
Control and coordination (or response to stimuli) is a process which helps the living organisms to survive in the changing environment around them. The process of
