In what ocean zone do most organisms live?

Explanation: Areas just off of the coast, from the shoreline to the edge of the continental shelf tend to have the most marine life. This area is called the neritic zone. It extends from the intertidal zone to the edge of the continental shelf where the oceanic zone begins.

Why do organisms go between ocean zones?

Organisms that photosynthesize depend on sunlight for food and so are restricted to the photic zone. Since tiny photosynthetic organisms, known as phytoplankton, supply nearly all of the energy and nutrients to the rest of the marine food web, most other marine organisms live in or at least visit the photic zone.

What special adaptations do organisms in the deep ocean zone have?

Animals in these areas of low to no light have many adaptations. Some have very large eyes to catch any small amount of light. Other emit their own light with bioluminescence, disguising their silhouette, attracting food or attracting a mate. It is thought that 90 percent of all deep sea animals have bioluminescence.

What factors affect the zones of life in the ocean?

In our oceans, there are a number of environmental conditions that affect the growth, survival and productivity of marine organisms. These include light availability, oxygen levels, water movement, salinity, density and pH.

What organisms live in the open ocean?

At this depth and pressure, the animals most commonly found are fish, mollusks, crustaceans, and jellyfish. Sperm whales will hunt at these depths on occasion to prey on giant squid.

What lives in the oceanic zone?

Animals such as fish, whales, and sharks are found in the oceanic zone.

How does the coastal ocean zone compare with the open ocean zone?

Even though the coast is just a small sliver of the ocean, it is the more productive of the two marine biomes. This means the coasts hold more marine biodiversity, which provides food for many animals, including humans. The open ocean stretches from the edges of the coast between the continents for hundreds of miles.

In which zone do some aquatic organisms rely on bioluminescence to entice prey?

Known as the twilight zone, the mesopelagic zone meets the photic zone above and becomes very dark as depth increases. Animals that produce bioluminescence, or light, inhabit this subzone. Because nutrients are limited here, some animals rise to the photic zone at night for food.

Which zone includes the whole ocean floor?

Some sunlight penetrates to the seabed here. The oceanic zone is the entire rest of the ocean from the bottom edge of the neritic zone, where sunlight does not reach the bottom.

How marine organisms adapt to the surface of the ocean?

Temperatures vary dramatically between the surface and the ocean floor. Marine life has developed many adaptations to the variations in temperature. Many marine mammals have blubber for insulation from the cold, and some fish have an antifreeze-like substance in their blood to keep it flowing.

What do organisms living in the Abyssopelagic zone lack?

The abyssal zone depends on dead organisms from the upper zones sinking to the seafloor, since their ecosystem lacks producers due to lack of sunlight. As fish and other animals are removed from the ocean, the frequency and amount of dead material reaching the abyssal zone decreases.

How do ocean animals adapt to their environment?

Common oceanic animal adaptations include gills, special breathing organs used by some oceanic animals like fish and crabs; blowholes, an opening on the top of the head that's used for breathing; fins, flat, wing-like structures on a fish that help it move through the water; and streamlined bodies.

Do animals live in all levels of the ocean?

The ocean water column is made up of 5 zones. The sunlight zone, the twilight zone, the midnight zone, the abyss and the trenches. This zone extends from the surface down to about 700 feet. ... Most marine animals live in this zone and feed off of photoplankton (the basis of the ocean food chain) and smaller fish.

What animals live in the euphotic zone of the ocean?

The ocean life in the Euphotic zone include sharks, jellyfish, sea turtles, coral, and zooplankton. The reason why there are so many various life in this zone is because of its access to sunlight.

What is the name for an organism that lives on the ocean floor?

Benthos are living organisms on the ocean floor. Many benthic organisms attach themselves to rocks and stay in one place. This protects them from crashing waves and other water movements. Some benthic organisms burrow into sediments for food or protection.
