If you were descending through the ocean zones in a submersible, which would be the first zone you encounter that is entirely without light? abyssopelagic bathypelagic epipelagic mesopelagic

The correct answer is Bathypelagic.

Explanation:

As the depth of the ocean increases, the passage of light decreases.

Only a minimum light can be seen between 200-1,000 meters, and once reached 1,000 meters deep, the light is impenetrable.

The ocean is generally divided into three zones: epipelagic, mesopelagic and bathypelagic.

The epipelagic zone is located 200 meters above the ocean. The sunlight that enters there is enough for the growth of plants that produce the ocean's primary food.

The area between 200 and 1,000 meters is known as mesopelagic or crepuscular.

The light that penetrates this area is severely reduced, since the depth is greater. In this area the amount of living organisms is very small.

Finally in the bathypelagic zone located below 1,000 meters, the light is completely impenetrable. It is usually called the midnight zone, and the only light available there is generated by the organisms that inhabit it.
