Q: 1. What are living and non-living things?

Living things are organisms that show life processes like growth, movement, breathing, reproduction, and response to stimuli (e.g., humans, animals, and plants). Non-living things do not show life processes and do not grow or reproduce (e.g., rocks, air, water, and furniture).

Q: 2. What are the main characteristics of living things?

Living things: ✔ Grow over time. ✔ Need food and water for survival. ✔ Breathe to get energy. ✔ Move in some way. ✔ Reproduce and produce offspring. ✔ Respond to their environment (stimuli). ✔ Have a life span and eventually die.

Q: 4. Why is water considered a non-living thing, even though it is essential for life?

Water does not show any life processes like growth, breathing, or reproduction, so it is a non-living thing . However, it is very important for living things because all plants and animals need water to survive.

Q: 5. How do animals and humans breathe differently?

✅ Humans and most animals breathe using lungs and take in oxygen from the air. ✅ Fish breathe using gills , which extract oxygen from water. ✅ Insects breathe through tiny holes (spiracles) on their bodies.

Q: 6. Can a robot be considered a living thing?

No, a robot is a non-living thing because: ❌ It does not grow or reproduce. ❌ It does not breathe or need food. ❌ It only moves when programmed, but does not respond naturally like a living being.

Q: 7. Why do living things need food?

Food provides energy for: 🍽️ Growth 🏃 Movement 🧠 Body functions 💪 Survival and reproduction

Q: 8. What is the difference between natural and man-made non-living things?

✅ Natural Non-Living Things: Found in nature (e.g., water, air, rocks, mountains). ✅ Man-Made Non-Living Things: Created by humans (e.g., buildings, cars, furniture).

Q: 9. Why do living things have a life span?

Every living thing has a fixed period of life . 🧒 A human can live up to 70-80 years . 🌳 Some trees like banyan can live hundreds of years . 🐦 Small insects may live only a few days or weeks .
