What are Life Processes?
If an organism is alive, it must keep repairing and maintaining its structures. The maintenance functions of living organisms must go on even when they are not doing anything particular. The processes which together perform this maintenance job are called life processes.
Nutrition
Nutrition is the process of intake of nutrients (like carbohydrates, fats, proteins, minerals, vitamins and water) by an organism as well as the utilization of these nutrients by the organism.
Respiration
Respiration is the process by which the food taken through nutrition gets oxidized to release energy for various activities.
Transportation
In unicellular organisms a single cell carries out all the life processes as the cell itself is the organism. In advanced forms like the few-celled algae, protozoa, sponges, etc., the size of the organism ensures that all the cells are not very far from each other. The uptake of materials from the environment is through the general body surface and the transport within the cells is by diffusion.
Excretion
Excretion is the biological process by which living organisms remove waste products that are produced from their metabolic activities (like respiration and digestion) to maintain a stable internal environment.
