Neither, dark matter is an undetectable yet massive existence within our universe. It is spread out relatively smoothly, not bunching up in particular locations. For more information, search dark matter images (computer simulated), they help the visualization of it.

Black Holes' can 'eat' any type of matter in the Universe.
Black Holes
No. When more matter falls into a black hole, it only makes it bigger and gives it even stronger gravity.
Black holes are not made up of dark matter. Dark matter is a mysterious substance that makes up a large portion of the universe's mass, but black holes are formed from the collapse of massive stars.
After consuming all nearby matter, black holes continue to exist in space but may not be actively consuming more matter.
No. Once a black hole forms, its internal composition is not something that can be described in terms of the types of matter that we are familiar with in our day-to-day lives. Essentially, a black hole and everything it "consumes" is converted into gravitational energy; no solid or liquid or gaseous matter exists inside of it.
Stars & black holes.
Bursts of light from black holes are the result of the accretion (or "consumption") of matter by black holes. Quasars are an example of this.
black holes swallow all energy and matter around them, including electricity
No. Without matter there would be no black hole. The black holes confirmed to exist so far actually have a fairly large amount of matter (or mass) - at least 2-3 times the mass of our Sun. The largest black holes have millions or even billions of times the mass of our Sun.No. Without matter there would be no black hole.

No. Black holes exist where gravity is so powerful that nothing can get out, not even light. "Dark Matter" is a vague hypothesis about the need for some additional mass that needs to exist in the galaxy in order to explain the way the galaxy does behave. We're not sure that "dark matter" exists at all.
