๐ฌ Chapter: Life Processes (Class 10 Science) ๐ Short Notes ๐น 1. Life Processes Life processes are the processes which maintain body functions and are necessary for survival. Examples : Nutrition, Respiration, Transportation, Excretion ๐น 2. Nutrition Process of intake and utilization of nutrients. Types of Nutrition : Autotrophic : Organisms prepare their own food (e.g., plants) Heterotrophic : Organisms depend on others for food (e.g., animals) ๐ฑ Autotrophic Nutrition (Photosynthesis) Occurs in green plants Uses: Carbon dioxide + Water + Sunlight + Chlorophyll Produces: Glucose + Oxygen Equation : 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ (in presence of sunlight and chlorophyll) ๐น 3. Respiration Process of breaking down glucose to release energy. Types : Aerobic (with oxygen): More energy, end products = CO₂ + H₂O Anaerobic (without oxygen): Less energy, end products = alcohol or lactic acid Equation : Glucose → Energy + CO₂ + H₂O (aerobic) ๐น 4.
