What are the 3 life zones in the ocean?
The open ocean is divided up into three life zones, the euphotic zone, the bathyal zone and the abyssal zone.
Which zone is most life found in the ocean?
Of the open ocean zones, most life is found in the epipelagic zone. This is where light is able to penetrate the ocean, allowing for photosynthetic processes to take place. It extends roughly 200m or 650 feet below the surface. This zone may also be known as the euphoric zone, the sunlight zone, or the photic zone.
What are the four main life zones in the ocean and how do they differ from one another?
Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land.
What lives in the middle of the ocean?
The marine pelagic environment is the largest aquatic habitat on Earth, occupying 1,370 million cubic kilometres (330 million cubic miles), and is the habitat for 11% of known fish species. The oceans have a mean depth of 4000 metres….Forage fish.

What ocean zone do coral reefs live in?
photic zone
Coral Reefs. Coral reefs are ocean ridges formed by marine invertebrates living in warm shallow waters within the photic zone of the ocean. They are found within 30˚ north and south of the equator.
How are the ocean zones divided?
The ocean is divided into horizontal zones based on the distance from shore and the depth of water beneath: the intertidal, neritic, and oceanic. Most of the life forms in the oceans live in, or at least visit, the surface.
What are the zones of the open sea?
There are four ocean zones: the Sunlight zone, the Twilight zone, the Midnight zone, and the Abyssal zone.
