Question

What are other examples of positive feedback loops ,a part from fruit ripening,childbirth and blood clotting ?

Answer 1

Feedback is defined as the information gained about a reaction to a product, which will allow the modification of the product. Feedback loops are therefore the process whereby a change to the system results in an alarm which will trigger a certain result. This result will either increase the change to the system or reduce it to bring the system back to normal. A few questions remain: How do these systems work? What is a positive feedback? What is negative feedback? Where do we find these systems in nature?

Answer 2

Lactation – the child feeding stimulates milk production which causes further feeding (continues until baby stops feeding)

Ovulation – the dominant follicle releases oestrogen which stimulates LH and FSH release to promote further follicular growth
