Question

zone that is made up of the entire ocean floor; benthic; neritic

Explanation:

The benthic zone is defined as the ecological region that includes the entire ocean floor, from the shallowest coastal areas to the deepest ocean trenches. The neritic zone is the shallow part of the ocean above the continental shelf, not the entire ocean floor. So the correct term for the zone made up of the entire ocean floor is Benthic.

Answer:

1. Benthic
