Explanation:

To complete the Frayer Model for "Negative Feedback Loop", we analyze each section:

1. Definition (in your own words)

A negative feedback loop is a self-regulating process where a system’s output acts to reverse or dampen the initial change that triggered it, helping to maintain stability (e.g., in biology, ecosystems, or engineering systems).

2. Illustration (that represents the word)

Draw a circular diagram with:

• A starting “Stimulus” (e.g., “Body temperature rises”).
• An “Effector” action (e.g., “Sweating increases” to cool the body).
• An arrow showing the “Response” (e.g., “Body temperature decreases”) feeding back to reduce the original stimulus.
• Label the loop as “Negative Feedback” to show the corrective, stabilizing flow.

3. Examples

• Biology (Homeostasis): Body temperature regulation (sweating/shivering), blood glucose regulation (insulin lowers blood sugar when it’s too high).
• Ecology: Predator-prey cycles (e.g., if prey populations grow, predators increase, reducing prey numbers).
• Engineering: Thermostat-controlled heating (if room is too warm, the thermostat turns off the heater).

4. Non - examples (or the opposite of...)

• Positive Feedback Loops (these amplify change, not stabilize):
• Blood clotting (a small clot triggers more clotting).
• Childbirth (contractions stimulate more contractions until birth).
• Nuclear chain reactions (one fission triggers more fissions).

If you need help with a specific section (e.g., refining the illustration or adding more examples), let me know!
