Feedback Loop is the by which some of the output of a circuit, system, or device is returned to the input.
In Engineering point of View:
feedback loop means taking some output information of the system and comparing it with our desired response(in waht way system should behave) and now the error (ie. desired - obtained result) produced is feb to controller to decide some action to make the system(here any machine,motor etc..) to behave in what manner we needed.
in common sense:
if u r a speaker, then you get your validation of speech through the applauds of the audience which is the feedback. ie u r getting feedback and based on that you are improving your skills
Eg:
In a class, the teacher teaches a subject to the student.The output is the understanding of the student. To evaluate their understanding the teacher asks to give feedback from all the student(to write in the piece of paper about how he/she teaches ie whether it is fast or slow etc ) and based on the understanding the students give their individual feedback. with this the teacher correct and improves his/her teaching to make them fully understood.
here
teacher is controller
students are system
output is the understanding of the student
feedback is the performance of the staff given based on understanding of student
desired response- to make the student fully understood
error - desired response minus what student understood
ok if u find this answer is not understandable give me a feedback i will improve it ..
A feedback system, in general engineering terms, is a system whose output if fed back to the input, and depending on the output, your input is adjusted so as to reach a steady-state. In colloquial language, you adjust your input based on the output of your system so as to achieve a certain end, like minimizing disturbance, cancelling echo (in a speech system) and so on.

Ebay and other venues use a system of performance ratings to judge the reliability of trading partners.
If you have a mic and speakers and sound comes out of the speakers and that is picked up by the mic and fed in to the speakers again and amplified by the amplifier comes out of the speaker again and picked up by the mic the process repeat its self over and over again and that whats makes the screacing noise that is feedback and it can blow your speakers up.

A feedback loop is a mechanism that is used to maintain homeostasis. In layman's terms, it is a checks and balances system within the body to keep hormone levels even.
Answer :Water is continuously moving form the Earth's surface into the air, and from the air back onto the Earth's surface. This continuous movement of water is called the hydrologic cycle, or water cycle.
because it all leads back to number 1 the first thing on the cycle
No, snakes are not decomposers. They are important to the life cycle because they feed off rats and other small creatures.
water evaporates condenses and forms perception and falls back to earth to compleat the cycle
A comets orbit is considered a cycle because a comet circles back in an elliptical orbit.
feed back loop
It is regulated by various enzymes and negative feed-back mechanisms.
feed back loop
No cycle. Transpiration is part of the water cycle, and photosynthesis is what plants do to feed themselves.Carbon cycle involves both of them. Photosynthesis remove Carbon from atmosphere. Respiration release them back
it feed is mike
That is very hi tech question! There should be no role of any control center in negative feed back mechanism. Both should regulate each other. But then the control center is required to do the up regulation or down regulation in this negative feed back mechanism. For example your blood pressure may get set at higher level in case of chronic psychological stress. Such stress is so common now a days.
it uses positve feed back
