B. Match each example to the correct characteristic

1. Eating a slice of bread.
→ This is taking in food → Nutrition

2. Touching a hot pot and quickly moving your hand.
→ Response to a stimulus (heat) → Irritability

6. Using energy from the food we eat.
→ This involves breaking down food for energy → Respiration

7. Breathing out carbon dioxide
→ Release of waste gas → Excretion (Note: Carbon dioxide is a waste product of respiration)
