Diarrhea itself is not a negative feedback mechanism; rather, it is a symptom of an underlying issue, such as infection, food intolerance, or gastrointestinal disorders. Negative feedback refers to processes that help maintain homeostasis by reducing the output of a system when a certain threshold is reached. In the context of digestion, negative feedback mechanisms regulate factors like enzyme secretion and gut motility to maintain balance, but diarrhea is a disruptive event rather than a regulatory process.
negative feedback
Perhaps you don't understand the meaning of positive and negative feedback. Positive feedback keeps adding to a process. Negative feedback doesn't. If a person fills a bathtub, positive feedback will continue the filling even if it runs over. Negative feedback will turn the water off when the tub is filled. So, negative feedback maintains homeostasis. Homeostasis means "steady state". When a processes is completed, it turns it off. Example: Blood sugar levels remain in a certain range.
An example of negative feedback would be a secretion of greater amount of insulin to lower the blood sugar level, and then secretion of greater amount of glucagon to increase the blood sugar level, and then a secretion of a greater amount of insulin to lower the blood sugar level..... etc.
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.

Is the clotting of blood an example of positive or negative feedback?

Negative feedback is a process that happens when your systems need to slow down or completely stop a process that is happening. When you eat, food travels into your stomach, and digestion begins. You don't need your stomach working if you aren't eating. The digestive system works with a series of hormones and nervous impulses to stop and start the secretion of acids in your stomach. Another example of negative feedback occurs when your body's temperature begins to rise and a negative feedback response works to counteract and stop the rise in temperature. Sweating is a good example of negative feedback.
Control of blood pressure.
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
Urinating is not an example of negative feedback. Negative feedback is a process that uses the result of a process to regulate the process itself, maintaining homeostasis. Urinating is a normal physiological process to eliminate waste and regulate fluid balance in the body.

It will make the itch a lot worse.
A negative feedback would be if the planet heats up, the glaciers will melt, lowering the albedo effect of the snow, and in turn causing the planet to heat up more That is positive feedback, not negative. Positive feedback enhances the initial stimulus, negative feedback reverses the initial stimulus. The planet starts by heating up, then heats up even more, which is positive feedback.
