Which option best describes the neritic zone ecosystem in marine aquatic biomes?
A
The deep-sea benthic environment below the photic zone, where sunlight does not penetrate
B
The estuarine zone where freshwater from rivers mixes with seawater, creating brackish conditions
C
The shallow coastal ocean over the continental shelf, extending from the low-tide line to the shelf break
D
The open ocean beyond the continental shelf, characterized by deeper water and lower nutrient availability near the surface
Verified step by step guidance1
Identify the key characteristics of the neritic zone in marine ecosystems, focusing on its location relative to the coastline and depth.
Recall that the neritic zone extends from the low-tide mark out to the edge of the continental shelf, which is relatively shallow compared to the open ocean.
Understand that this zone receives ample sunlight, supporting photosynthesis and a rich diversity of marine life, distinguishing it from deeper zones where light penetration is minimal or absent.
Compare the neritic zone to other marine zones mentioned: the deep-sea benthic environment (deep and dark), the estuarine zone (where freshwater mixes with seawater), and the open ocean beyond the continental shelf (deeper and nutrient-poor).
Conclude that the neritic zone is best described as the shallow coastal ocean over the continental shelf, extending from the low-tide line to the shelf break, due to its depth, light availability, and proximity to land.
