Nutrition is the process by which organisms obtain and utilise food for energy, growth, and repair. Plants are autotrophic and prepare their own food through photosynthesis using sunlight, carbon dioxide, and water. Animals are heterotrophic and depend on plants or other animals for food. Transportation is the movement of water, minerals, and food within organisms. In plants, xylem transports water and minerals from roots to leaves, while phloem transports food from leaves to other parts. This Nutrition and Transportation Quiz for Class 8 examines these vital life processes in both plants and animals. In animals, the circulatory system transports nutrients, gases, and wastes using blood. Respiration is the process of breaking down food to release energy. It involves inhalation of oxygen and exhalation of carbon dioxide. Learning about these life processes helps students understand how organisms sustain life and maintain their functions. Take these 10 questions to test your knowledge.
