Life Processes in Science
Updated on May 11, 2025 | By Learnzy Academy
Life processes are the essential activities that all living organisms perform to stay alive. These processes help organisms to grow, get energy, remove waste, and reproduce.
Main Life Processes:
- Nutrition – Taking in food and using it for energy and growth.
- Respiration – Breaking down food to release energy.
- Transportation – Movement of food, water, and other substances inside the body.
- Excretion – Removal of waste products from the body.
These processes are continuous and necessary for the survival of all living beings.
Example: Humans eat food (nutrition), breathe in oxygen (respiration), blood carries nutrients (transportation), and kidneys remove waste (excretion).
