Read each question carefully and answer to the best of your ability. This worksheet will test your understanding of feedback loops in living organisms.
1. Which type of feedback loop works to maintain a stable internal environment (homeostasis)?
Positive feedback
Negative feedback
Neutral feedback
Circular feedback
2. Childbirth is an example of which type of feedback loop?
Positive feedback
Negative feedback
Regulatory feedback
No feedback
3. When your body temperature rises, your body sweats to cool down. This is an example of a feedback loop.
4. A feedback loop that amplifies a change is called a feedback loop.
5. Negative feedback loops are rare in biological systems.
True
False
6. A positive feedback loop always leads to a stable condition.
True
False
Match the feedback loop type with its description.
7. Negative Feedback
a. Amplifies a change
8. Positive Feedback
b. Reduces or reverses a change
9. Describe a real-life example of a negative feedback loop in the human body, and explain how it works.
