In this Class 10 Science topic from the chapter “World of Living,” students explore the essential processes that keep organisms alive and functioning. They learn how plants and animals obtain and use nutrition, release energy through respiration, transport substances such as water, minerals, gases and food, and remove metabolic wastes through excretion. The topic connects these ideas with photosynthesis and the roles of major human body systems, helping students understand how living organisms maintain life through coordinated biological activities.
