Life processes refer to the essential activities that living organisms perform to survive. These activities include nutrition, respiration, transportation, excretion, regulation, and reproduction.
Nutrition: This involves the process of taking in food and converting it into a form that can be used by the body. It includes two types: autotrophic nutrition, where organisms make their own food, and heterotrophic nutrition, where organisms obtain food from external sources.
Respiration: This is the process of breaking down food molecules to release energy for the body to use. It involves the intake of oxygen and the release of carbon dioxide.
Transportation: This refers to the movement of substances such as nutrients, gases, and waste products throughout the body. In plants, transportation takes place through the xylem and phloem tissues, while in animals, it occurs through the circulatory system.
Excretion: This involves the removal of waste products from the body. In plants, waste products are eliminated through the stomata, while in animals, they are eliminated through organs such as the kidneys.
Regulation: This refers to the maintenance of a stable internal environment in the body, known as homeostasis. It includes processes such as temperature regulation, pH balance, and water balance.
Reproduction: This involves the production of offspring to continue the species. It includes two types: asexual reproduction, where a single organism produces offspring that are genetically identical to itself, and sexual reproduction, where two parents contribute genetic material to produce offspring that are genetically diverse.
In summary, these life processes are vital for the survival and maintenance of all living organisms.

Verified answer
• The maintenance of living organisms is essential
even if they are moving, resting or even sleeping.
The processes which together perform the function of maintenance of ‘life’ are called as life processes.
• Nutrition, respiration, circulation, and excretion are examples of essential life processes.
In unicellular organisms, all these processes are carried out by a single cell.
In multicellular organisms, well-developed systems are present to carry out the processes.
IN SHORT THE PROCESSES REQUIRED FOR LIVING ORGANISMS TO SURVIVE IS KNOWN AS LIFE PROCESSES.
