What are the zones in a marine ecosystem based upon?
Zones Based on Depth of Water
Scientists refer to the vertical extent of ocean water as the water column. Two main zones based on depth of water are the photic zone and aphotic zone. The photic zone is the top 200 meters of water. The aphotic zone is water deeper than 200 meters.
What are four types of marine saltwater ecosystems?
Although there is some disagreement, several types of marine ecosystems are largely agreed on: estuaries, salt marshes, mangrove forests, coral reefs, the open ocean, and the deep-sea ocean. An estuary is a coastal zone where oceans meets rivers.

How many zones are in the marine ecosystem?
Water/Pelagic environment consists of two major marine ecosystems, Neritic and Oceanic zones. Bottom/Benthic environment consists of the other three major ecosystems, Supralittoral, Intertidal/Littoral, and Sublittoral zones. The major five marine ecosystems nurture almost half of the identified species on Earth.
How many zones are there in the ocean?
The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it.
How are ocean zones classified?
Two ways oceanic zones are classified are by vertical zones, the different zones found as you move from the surface of the water to the ocean floor, and horizontal zones, the different zones found moving from shore outward. … Pelagic zone: The area from the low tide marks out into the open ocean.
What’s in a marine ecosystem?
The marine ecosystem includes: marshes, tidal zones, estuaries, the mangrove forest, lagoons, sea grass beds, the sea floor, and the coral reefs. Just like every other ecosystem in the world, the aquatic ecosystems rely on each other for maintaining a balanced marine ecosystem.
What are the types of marine biomes?
Marine biomes include the oceans, coral reefs, and estuaries.
