What are abiotic factors in the neritic zone?

Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature.

What are the biotic factors in the ocean?

Biotic factors include plants, animals, fungi, algae, and bacteria. Abiotic factors include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability. Ocean ecosystems are impacted by abiotic factors in ways that may be different from terrestrial ecosystems.

What organisms live in the neritic zone?

Animal, protist, and plant life in the neritic zone include fish, crustaceans, mollusks, marine mammals, algae, kelp, and seagrass.

What type of fish live in the neritic zone?

Aside from the above, the zone supports a wide range of fish species including bluefin tuna, herring, capelin, mackerel, and many more species. The plankton attracts smaller fish, which attract larger fish who complete the web. Larger species include blue whales, humpback whales, whale sharks, and others.

What are biotic factors in the Twilight Zone?

Biotic. The Biotic Factors of the Twilight Zone include the following: Angel Shark, Brittle Star, Coleacanth, Gray Whale, Hermit Crab, Jelly Fish, Lobster, Puffer Fish, Plankton, and last but not least Octopus.

What are 10 biotic factors in the ocean?

Other creatures in the ocean include jellyfish, octopus, sea turtles, squid, lobsters, shrimp, krill, marine worms, eels, plankton, starfish, seahorses, sea cucumbers and sand dollars. Kelp, seaweed, algae and coral are some of the plants that live in the ocean.

What is neritic zone of ocean?

neritic zone, shallow marine environment extending from mean low water down to 200-metre (660-foot) depths, generally corresponding to the continental shelf. Neritic waters are penetrated by varying amounts of sunlight, which permits photosynthesis by both planktonic and bottom-dwelling organisms.

What are the two main habitats of the neritic zone?

Two habitats found in the neritic zone are kelp forests and coral reefs. Kelp forests are found in cold waters. Kelp are large, plantlike algae with holdfasts that anchor them to the rocky ocean bottom. Coral reefs are found in warm, shallow waters.

How are organisms adapted to neritic zone?

Neritic/Epipelagic Zone Animal Adaptations: Buoyancy Many organisms living in the neritic zone have developed adaptations for buoyancy. Some organisms need to float to conserve energy, while others need to float to feed near the surface in shallow waters. Buoyancy adaptations vary with species.

What are the physical conditions in the neritic zone?

Physical characteristics The neritic zone is covered with generally well-oxygenated water, receives plenty of sunlight, is relatively stable temperature, has low water pressure and stable salinity levels, making it highly suitable for photosynthetic life.

What is a neritic zone in the ocean?

Neritic zone. Neritic zone, shallow marine environment extending from mean low water down to 200-metre (660-foot) depths, generally corresponding to the continental shelf. Neritic waters are penetrated by varying amounts of sunlight, which permits photosynthesis by both planktonic and bottom-dwelling organisms.

Biotic Factors in the Ocean. Saline oceans cover about 71% of the Earth’s surface and hold 97% of the planet’s water. The oceans are home to around 230,000 species of organisms. Some of the mammals that live in the ocean are whales, seals, sea lions, dolphins, sharks, porpoises and walruses.

What are the biotic communities of the neritic zone?

The biotic communities of the neritic zone consist of the following groups. 1. Producers: The dominant producers in the neritic zone are passively drifting or floating algae, called phytoplankton, although in some locations the algae attached to the bottom also become important as producers.

Why is the neritic zone so important for fish?

It has been estimated that 90% of the world’s fish and shellfish harvest comes from the neritic zone. The stable environment of this zone provides light, oxygen, nutrients contributed by runoff from nearby land and up-welling from the continental shelf, as well as suitable salinity and temperature to support a wide range of marine life.
