Final answer:
The large amounts of detritus along with primary production make these areas some of the most productive in the marine environment.
Step-by-step explanation:
The large amounts of detritus along with the primary production that does occur makes these areas some of the most productive in the marine environment. The neritic zone, which includes the shallow ocean ecosystems, is known for its high productivity and biodiversity. Phytoplankton, zooplankton, and other marine organisms contribute to this productivity.
