Examples are seen in the Ang B , Hyal b , and Trim A intervals ( wells 5 through 11 , pl . Small drifting animals, called zooplankton, consume small producers and serve as prey for many fish and invertebrates. Those species are an important food source for humans, but other neritic fish are popular in the pet trade. Marine sediments provide valuable clues about which of the following Earth history events? The benthic zone is subdivided into different zones, namely intertidal or littoral zone, supralittoral zone, sublittoral zone, bathyal zone, abyssal zone and hadal zone. What conditions are necessary for siliceous ooze to accumulate on the seafloor? Most corals secrete calcium carbonate exoskeletons, forming large coral reefs when they grow together in colonies. Nutrients are required by all of the marine primary producers. The neritic zone is shallower and closer to shore than the oceanic zone. Space dust, asteroids and meteorsform cosmogenous sediment.
