Many animals living in the deep ocean rely on dead animals falling from the water column as food. These include bacteria, archaea, protozoa, eukaryotes, and metazoans, all of which live in symbiotic relationships with the organisms that live below the surface.

How deep can you fish in the ocean?
According to a new study, fish can’t live any deeper than 8200 meters. The new research, published today in the journal Proceedings of the National Academy of Sciences, suggests that deep-sea fish may not be able to survive at such depths because they lack the ability to metabolize carbon dioxide, a byproduct of photosynthesis.
Instead, they rely on a chemical called nitrate, which is found in seawater and can be used as a source of energy. Nitrate can also be converted to nitrite, an even more potent form of nitrogen that is used to make nitric acid, the main ingredient in fertilizers and other chemicals that are used in agriculture and industry.
But the nitrates that fish use to produce nitrous oxide—a potent greenhouse gas—don’t come from the ocean. They’re produced by bacteria living on the seafloor, and the researchers found that these bacteria don’t have the enzymes needed to convert the nitrogen back into nitrogen dioxide.
Are there sharks in the middle of the ocean?
The sharks are attracted to the warm water, which is rich in nutrients and oxygen, as well as the food they can find on the ocean floor. The sharks also feed on small fish, squid, and crustaceans. In the past, the sharks have been known to attack humans, but this is the first time they have attacked a ship.
Which part of the ocean is suitable for fishing?
The atlantic ocean has a coastline of 111,000 kilometres, making it the second- largest ocean. It is a small part of the Earth’s surface. The waters off the coast of Africa, the Middle East and Asia are home to some of the world’s richest fishing resources.
What’s in the deepest part of the ocean?
The depression in the Earth’s crust is nearly 36,700 feet deep. The deepest part of the ocean is made up of the mariana trench. The exact depth of the Mariana Trench remains a mystery, but it is believed to be at least 3,000 feet below sea level. The deepest point on Earth is the Challenger Deep, which is located off the coast of South Africa.
How much of the ocean is undiscovered?
More than eighty percent of the ocean is unexplored. The deep ocean has many mysteries to be learned. (DEEPOP) is a partnership between the National Oceanic and Atmospheric Administration (NOAA), the U.S. Geological Survey (USGS), and the University of California, Santa Barbara (UCSB).
The goal of this program is to explore the ocean floor in a manner that will enable us to better understand the processes that drive the evolution and evolution of life on Earth.
What happens if a fish swims too deep?
Chris lowe, a marine scientist at california state, long beach, that barotrauma can cause a fish’s eyes to pop out of its head and its stomach to be pushed out of its mouth. He said sport fishermen unintentionally kill millions of deep-water fish they don’t want to eat.
“It’s a huge problem,” Lowe told Live Science in an email.
