Answer:
>>>steady nutrient supply
>>>>ample sunlight
Step-by-step explanation:
The neritic zone lies in the continental shelf and it extends from the surface to about a depth of 200m. Below the neritic zone is the bathyal zone.
The neritic zone is a shallow zone of water. It is sunlit and it receives ample solar insolation all year round. The salinity of this zone is very stable. This makes for organims to thrive. The neritic zone is home to diverse aquatic life. Due to the ample sunlight available here, photosynthetic rate is very high.
Due to high insolation in this region of the ocean, surface temperature is very high. The deeper we move in the ocean, the colder the water body becomes.
