Answer: Life process is the basic activity performed by living organisms to maintain life. These include nutrition, respiration, transportation, excretion, reproduction, and growth. These processes help organisms obtain energy, remove waste, and sustain life. All living beings carry out life processes to survive, grow, and respond to their environment.
Explanation:
Life process refers to the essential biological activities that all living organisms perform to stay alive. These processes include nutrition, respiration, transportation, excretion, growth, reproduction, and response to stimuli. Each of these is vital for the survival and proper functioning of the organism.
Nutrition is the process by which organisms obtain food and convert it into energy. Plants use photosynthesis (autotrophic nutrition), while animals take in ready-made food (heterotrophic nutrition).
Respiration is the process of breaking down food (mainly glucose) to release energy, usually in the form of Adenosine Triphosphate (ATP). It can be aerobic (with oxygen) or anaerobic (without oxygen).
Transportation involves the movement of essential substances like water, minerals, and nutrients within the body. In humans, blood circulates these materials; in plants, xylem and phloem carry water and food.
Excretion is the removal of waste products produced during various metabolic activities. Humans excrete through kidneys, while plants use other methods.
These life processes ensure that an organism can grow, reproduce, and respond to its environment. Without these processes, life cannot be sustained. All living beings, from single-celled organisms to complex animals and plants, perform these activities in some form.
