Answer :
Final answer:
The abyssopelagic zone is a part of the ocean that is extremely cold, under high pressure, and devoid of light and plants. It is inhabited by organisms that have adapted to survive in these harsh conditions.
Explanation:
The abyssopelagic zone is the
portion of the ocean that extends from a depth of about 4,000 to 6,000 meters
(13,000 to 20,000 feet) below the surface. It is also known as the abyssal zone
and is characterized by extreme cold temperatures, high pressure, complete darkness,
and a lack of plants due to the absence of sunlight.
In the abyssopelagic zone, the water temperature
remains around freezing point, reaching around 0 to 3 degrees Celsius (32 to 37
degrees Fahrenheit). The immense pressure is generated by the weight of the water
column above, which can be up to 600 times greater than at sea level.
Due to the
absence of sunlight, there is no photosynthesis occurring in the abyssopelagic
zone. This means that there are no plants or algae present, and the primary food
source is organic material that falls from the upper layers of the ocean.
Organisms found in this zone have adapted to survive in these extreme conditions,
such as deep-sea fish, amphipods, and giant squid.
