Organisms Ocean Floor Are Called

Plate tectonics and the ocean floor.

Organisms ocean floor are called.

The area along the ocean floor that consists of sand silt and dead organisms is called the benethic zone. Microscopic plants and animals called plankton live on the surface of. Ooze is described as the remains of that settle on the ocean floor. Separated into two new genera these organisms are a type of xenophyophores that live on the ocean floor and form elaborate shell like exoskeletons called tests from the environment around them.

Nearly half of the world s sea floors are over 3 000 meters 9 800 ft deep. Contrary to popular belief most of the sea floor known as the open ocean is not really a habitat for animals just a place they pass by on the way to somewhere else. A person who studies ocean life is called a marine biologist. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle.

Fish and other animals make their homes in all different parts of the ocean even on the bottom or sea floor. In total 4 4 10 20 nematodes inhabit the earth s topsoil or approximately 60 billion for each human with the highest densities observed in tundra and boreal forests.
