The neritic zone is the zone in the water bodies that is by far the richest in marine life. This zone is occupying the shallowest part of the oceans, representing the waters above the continental shelf up until the drop off of the continental shelf, having maximal depth of roughly 200 meters. This makes this zone very good for the marine life because of two major reasons, one being the sunlight, and the other being warmth of the water. Because the neritic zone is shallow, the sunlight manages to penetrate through it, thus it enables the producers to be able to perform photosynthesis. Since the producers are the basis of all ecosystems as they are the ones that produce the most energy and are primary food source, that means that all the other organisms can prosper as well. Also, the fact that this zone is shallow means that the water is warmer, as the sunlight manages to affect most of it, thus making it warmer and much better for life than the other deeper zones that are much colder.
