Disk galaxies are dynamic ecosystems of many species. I will review recent X-ray observations that reveal an otherwise hidden species and its energetic interplay with other components of such galaxies. I will focus on answering four questions: 1. How do X-ray properties vary among galaxies? 2. Does the X-ray emission trace the accretion or feedback of galaxies? 3. What is the nature of the X-ray emission? 4. How can one conduct an X-ray tomography of a galaxy? In particular, I will demonstrate that such X-ray observations are a key to solving mysteries of galaxy formation and evolution.
