Detailed explanation-1: -Abyssopelagic Zone The water in this zone is extremely cold and has very little oxygen in it. It is also completely dark and under very high pressure.

Detailed explanation-2: -The benthic zone is the lowest ecological zone in a water body, and usually involves the sediments at the seafloor. These sediments play an important role in providing nutrients for the organisms that live in the benthic zone.

Detailed explanation-3: -Temperature in the benthic zone ranges from warmer temperatures at shallow depths because of close proximity to the water surface, but may drop to 2 °C to 3 °C at the most extreme depths of the abyssal zone. At such cold temperatures, abundance of life is quite low and organisms move at a very slow pace.

Detailed explanation-4: -Benthos that are found on the ocean floor are known as epifauna, while those found at greater depths are known as infauna.
