Does feedback exist in nature?

If you think about how within an organism and outside an organism, things interact, and there are signals that are always sent. So currently, your body's producing a plethora of hormones and you have these binding receptors that those hormones sort of bind to, to be able to send these specific signal to particular parts of your body and cells. Similarly, in the world of building a business or just building something as part of a team, there are signals you need to be receptive of to be able to do your work properly. And that feedback, whether what we call biological feedback or feedback within an organisation are exactly the same. And without that feedback, there is no such thing as improvement or progress.
