Let's solve this step by step.

Part 1: Match Column A to Column B

We need to match each statement in Column A with the correct life process from Column B.

#### Column A → Column B

1. Humans and animals eat plants for energy.
→ This is about obtaining food for energy.
✔ D. FEEDING

2. Plants take in carbon dioxide from the atmosphere and release oxygen.
→ This describes respiration or gas exchange, which is part of breathing.
✔ F. BREATHING

3. Plants get rid of waste through the process of transpiration.
→ Transpiration removes excess water and helps in waste removal. This is a form of excretion.
✔ E. EXCRETING

4. Plants turn towards the sunlight or water.
→ This shows a response to stimuli (light/water), so it’s sensing.
✔ G. SENSING

5. Some animals hibernate in the winter.
→ Hibernation is a way animals respond to environmental changes (cold). It involves movement (inactivity) but more importantly, it's a response to stimuli — sensing.
✔ G. SENSING

6. Humans and animals have offspring (babies)
→ This is clearly reproduction.
✔ A. REPRODUCING

7. A seedling grows into a plant.
→ This is growth.
✔ C. GROWING

Part 2: Identify the Life Process in the Pictures

Now let's analyze the pictures below and label them with the correct life process.

#### Picture 1: Lungs
- Shows lungs — involved in gas exchange (taking in oxygen, releasing CO₂).
- ✔ F. BREATHING

#### Picture 2: Seedling growing into a plant
- A seed sprouting and growing — this is growth.
- ✔ C. GROWING

#### Picture 3: Lion eating prey
- An animal feeding on another organism — feeding.
- ✔ D. FEEDING

#### Picture 4: Person eating food
- Eating a meal — taking in nutrients.
- ✔ D. FEEDING

#### Picture 5: Tree shedding leaves
- Losing old leaves — this is excretion of waste materials.
- ✔ E. EXCRETING

#### Picture 6: Person running
- Movement — physical activity.
- ✔ B. MOVING

---

✔ Answers for the Pictures:

1. Lungs → F. BREATHING
2. Seedling → C. GROWING
3. Lion eating → D. FEEDING
4. Person eating → D. FEEDING
5. Tree shedding leaves → E. EXCRETING
6. Running person → B. MOVING
