What does instinct mean?
An instinct is an urge or idea to do something, and that instinct is a natural part of who you are... not something you have to think about much. Instincts can be inborn, or developed through the way you live. For instance, a man living in the woods might have developed better survival instincts than a tourist if both were attacked in the same woods.
A behavior is something you actually do. It has gone beyond the stage of wanting to do it or having the instinct to do it. Behaviors can be anything that you do... walking, rubbing your eyes... anything.
Behavior and instinct are different in the same way that desire
and action are different... you can really, really want a blueberry
muffin, but not take any action to get one. You can have a really
strong instinct to run away from a wedding, but go through with it
knowledge you can feel not learn
Well it depends on what instinct. I will guess you mean in a dangerous situation for a horse. If there is a frightening event a domesticated horse will usually gallop to their home, or most likely, the barn. That is very dangerous, especially if the barn has caught fire. But for a wild horse their first instinct is usually to run away.
