Detailed explanation-3: -Benthos that are found on the ocean floor are known as epifauna, while those found at greater depths are known as infauna.

Detailed explanation-4: -Types of Benthic Zone Bathyal zone (200 to 2, 000 m) Abyssal zone (2, 000 to 6, 000 m) Hadal zone (over 6, 000 m)

Detailed explanation-5: -Note: The term benthic refers to anything associated with or occurring on the bottom of a body of water. The animals and plants that live on or in the bottom are known as the benthos.
