the numbers of different species present and the range of habitats and ecosystems. (i.e.) Coral reefs have a high biodiversity with many different species present, whereas a sandy shore has a low biodiversity as there are relatively few different species in this habitat.
Which part 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.
Why do rocky shores have higher biodiversity than sandy shores?
-Sandy shores are unstable due to the surface, as the fine mineral particles are easily moved by winds and tides; however, rocky shores are very stable and are able to support a multiple variety of marine organisms.
Why do hydrothermal vents have low biodiversity?
The water surrounding hydrothermal vents is under very high pressure and at a high temperature; relatively few organisms are adapted to survive in these conditions.
Why do sandy beaches tend to have low biodiversity?
Some environments that are unstable or extreme tend to have low biodiversity. Sandy shores dry out easily and is constantly eroded by wind and water, making it very difficult for organisms to survive. … Organisms with specialized niches have a narrow range of food or live in a specific habitat.
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.
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.
Do rocky shores have high biodiversity?
Rocky shores are biologically rich environments. Species here have become adapted to deal with the extreme conditions created by the movement of the tides and many cannot be found anywhere else.
What is the difference between rocky shores and sandy beaches?
Rocky shores are a strong contrast with sandy beaches. On sandy shores, the substrate is shifting and unstable. … Physical conditions are relatively uniform because waves shape the substrate. On rocky shores, by contrast, the physical substrate is by definition hard and stable.
What is a big difference between rocky shores and other marine ecosystems?
Unlike coral reefs, mangrove forests, and several other marine ecosystems, rocky shores are not directly created by living organisms. Therefore, providing protection for these areas is different than for those other systems.
Do species in habitats with high biodiversity have specialized or generalized niches?
A generalized niche has a wide range of foo sources and a wide range of habitat. For example, tuna. High biodiversity means that many different species live within one habitat. Areas of high biodiversity tend to have narrow niches because it niches overlap, individuals will die out.
Do hydrothermal vents have low biodiversity?
From a biogeographic standpoint, deep-sea hydrothermal vents occur as small island-like habitats scattered widely across the deep seafloor. Individual vents often have low diversity, supporting a limited number of species.
How do hydrothermal vents affect biodiversity?
Relative to the majority of the deep sea, the areas around submarine hydrothermal vents are biologically more diverse and productive, with a high degree of specialisation and species endemism. Almost nothing is known about how these vent assemblages form, recruit, spread or maintain themselves.
