Which layer of the ocean has the greatest biodiversity?

The epipelagic zone stretches from the surface down to 200 m and is home to the greatest biodiversity in the sea, largely because of the availability of sunlight that enables photosynthetic organisms to thrive. Both marine plants and animals are found here.

Which layer of the ocean has the most biodiversity?

The epipelagic zone extends from the surface to 200m down. It receives plenty of sunlight and therefore contains the most biodiversity in the ocean.

Which area would have the greatest biodiversity?

The parts of the Earth with the greatest biodiversity exist along the equator in tropical rainforests and coral reefs.

Where is marine biodiversity the greatest?

The greatest marine biodiversity occurs in coral reefs, estuaries, and on the deep-sea ocean floor. 2. Biodiversity is higher near the coasts because of great variety of producers, habitats, and nursery areas.

What regions of the ocean have the highest biodiversity?

Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.

Which ocean has the most coral reefs?

The Pacific Ocean has the most coral species.

Because of these environmental restrictions, reefs generally are confined to tropical and semitropical waters.

What is ocean biodiversity?

Marine biodiversity therefore refers to the species richness and abundance in the world’s oceans and seas. And since the world is covered with approximately 70% water, the amount of life in the oceans is enormous. … Protection of water resources (e.g. Mangrove forests trap silt)

Does the ocean have a high biodiversity?

In its simplest form, biodiversity or biological diversity is therefore ‘Life on Earth’ and includes marine biodiversity ‘Life in the Seas and Oceans. ` The marine environment has a very high biodiversity because 32 out of the 33 described animal phyla are represented in there.

Where are the liveliest ocean biodiversity hotspots?

While scientists in the past have identified key areas of biodiversity, the new work is more detailed. Researchers found the liveliest ocean hot spot also happens to be where the science of evolution sprouted: the Pacific Ocean off the central South American coast.

Which ocean zone has the least biodiversity?

The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round.

What is high biodiversity?

High biodiversity is a habitat or ecosystem that has a high number of different species.

Why do coral reefs have a high biodiversity?

Coral reefs have high levels of biodiversity because of their abundant microhabitats, high levels of nutrients, and high levels of sunlight and warm…
