Which term refers to the seabed community and environments?

• A. Autotroph
• B. Bathyal Zone
• C. Abyssal Zone
• D. Benthic

Answer: (D)

The main idea is describing the bottom-dwelling part of a marine ecosystem. The term that refers to the seabed community and environments is benthic. It specifically describes organisms that live on, in, or associated with the seabed, and the habitats they occupy on the ocean floor. The other terms describe either what organisms do (autotrophs produce their own food) or which depth zone they inhabit (bathyal and abyssal refer to depth), not the bottom-based community itself. So benthic best captures the concept of the seabed community and its environments.
