Consider a newborn squirrel born and raised in a bare cage on a liquid diet. at some point you present it with an acorn for the first time. the squirrel takes it to one corner of the cage and attempts to bury it. name the type of behavior you have witnessed.

I believe the answer is: innate behavior
innate behavior refers to the type of behavior that biologically hardwired to each organisms.
This hardwired behavior is usually formed without having to be conciously learned and important in order to improve the organisms' chance in surviving within their environment.
