Biological systems are really wacky from an input -> magic - > output point of view. The levels of gene expression (as in, how much of that sweet transcription and translation is happening) on a certain sample may change based on the presence or not of external stimuli, and even the genetic expression may change based on other genes' expression (see gene regulatory networks). There is a lot of "intelligent" biological behaviour out there that is not conscious. Now if only we could come up with some decent definition for consciousness :/
