It converts it into gravitational energy.
A black body absorbs most of the light that falls on it. A perfect black body will absorb all of the light but will radiate electromagnetic energy according to it's temperature according to plank's law. This is why we call a black hole a BLACK hole. It absorbs EVERYTHING which falls into it and not even light can escape.
Black absorbs energy, other colors reflect more energy (you see a color or a white sheet)
Black
No, nothing can escape a black hole
Absorbs
No. The only thing "in" a black hole is pure gravitational energy.
Particles falling into a black hole release a large amount of x-rays as they do so. This is not energy from the black hole itself, but energy release that is a sign of a black hole.
No, it does not appear to have a giant cross. It is called a "Black" hole because it absorbs all the light that hits the horizon, reflecting nothing.
The sun's energy has not formed a black hole.
A black hole sucks all the mass and energy which passes it, even light. So it's called black hole.

When a star of sufficient mass stops producing energy, it will collapse into a black hole.
