What is the term used for an organism that can see well in both light and dark?

I believe such an animal the term low-light vision is used. Such as an owl. Most birds are sight-driven and have excellent vision. The owl has excellent day vision and excellent night vision because its pupils can dialte to allow moonlight or starlight sufficient lighting to see by. This is not to be confused with infravision which is totally different than low-light vision. That would allow the heat an animal gives off to be seen in the dark.

people call "dark" what they cannot "see"".To "see" means to detect by means of their eyes that part of electromagnetic waves which we call "visible light".But there is much more "energy" than that.

bioluminescence (bī'ōlū'mĭnĕs'əns) , production of light by living organisms. The production of light in bioluminescent organisms results from the conversion of chemical energy to light energy. Dinoflagellates have an interesting twist on this mechanism. When a predator of plankton is sensed through motion in the water, the dinoflagellate luminesces. This in turn attracts even larger predators which will consume the would-be predator of the dinoflagellate.

Yes!  Dark is untill you are able to see and distinguish things in the room.  You could be half blind and see the room dark at normal lights but if more lights are brought in, you see the room perfect.

Cyanobacteria can use sunlight or organic materials to survive, while algae must have sunlight.

Chlorophyll. It needs the presence of sunlight too.

We have two types of receptors (light-sensitive nerve cells) in the retina of the eye.  The two types are called 'rods' and 'cones.'  The 'rods' (so-called because of their shape) respond to low-levels of light and are useful for night vision.  However, since all rods are pretty much identical, they do not distinguish between colors ... our dim-light rod vision is "black and white."\n\nThere are three types of cones (again, so called becaues of their shape).  One responds to long-wavelengths of light, what we call the "reds".  One responds to medium-wavelengths, what we call "greens".  And the third responds to short-wavelengths (the highest energy), what we call the "blues" (unless you live in Mississippi, then the "blues" is something different :-) ).  \n\nThese ranges of wavelengths for the three types of cones are not exclusive ... they overlap.  In other words, the long-wavelength cones also respond to medium wavelengths, although to a lesser extent.  Because they overlap, every object that gives off different mixtures of wavelengths affect the different cones by different amounts.  This experience is what we call color.  (Unless you live in Britain.  They don't see in colors.  They see in colours.)

The answer is D.  Animals with large eyes (think owls) are usually nocturnal.   Larger eyes allow for more light to come in.

There are viper fish, deep sea anglers, and brotulids to name a few. Some are blind but some have bioluminescence, or in other words they can glow in the dark and have huge eyes. They came to live so deep very gradually over millions of years.
