Yes.
Black objects absorb all or most of the visible wavelengths of light, whereas white objects reflect all wavelengths. When all visible wavelengths (violet to red) enter the eye in equal proportions, the color is perceived as white. When no wavelengths reach the eye, the color is perceived as black. Every other color is a mixture of this continuum of wavelengths.
Be careful not to confuse: Opaque objects are those that do not allow light to pass through it, but they can reflect light. It is BLACK objects that absorb all the incident light on it. To conclude, opaque objects do not necessarily absorb all the incident light on them but black objects ABSORB all the incident light on them (and are, of course, opaque)
All objects do. There is none that does not absorb any.
All visible objects with a defined color absorb colours of the sunlight. If you see e.g. a red box, it absorbs all the green and blue parts of the sun light. While black objects absorb all colours (and therefore get most hot), white objects absorb almost nothing, so keeping cool.
Yes.
Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light.

The "color" black is not really a color. Black is the absence of light. Black objects have pigments that absorb all light and, therefore, none is reflected for us to be able to see.
Black objects absorb all wavelengths of visible light and are therefore dark.

Since blue objects absorb the green light, the objects appear black.
Since an object is observed as the color(s) it reflects, a green object absorbs all colors and reflects green.

It doesn't absorb ALL of it just a little is reflected.
