We know very well that ocean is the most deepest and biggest source of water so oceans are the home to many aquatic animal and plants…. we also know that there are many fishes that live in ocean. … If oceans isn’t there so where will these plants and animals live….that’s why it is the greatest biodiversity…
How is the ocean home to the greatest biodiversity?
Scientists estimate that 25 percent of all marine species live on coral reefs, making them one of the most diverse habitats in the world. Ocean life is not evenly distributed. Life in the euphotic zone is very diverse due to availability of sunlight and diversity of producers found in this zone.
Why is ocean life so diverse?
“The oceans we see today are filled with a dizzying array of species in groups like fishes, arthropods, and mollusks, not because they had higher origination rates than groups that are less common, but because they had lower extinction rates over very long intervals of time.”
How diverse is the ocean?
The world’s oceans contain somewhere between 500,000 and 10 million marine species. bacteria, other microbes and viruses. Much of the biodiversity in the ocean, particularly in the deep sea and in the microbial ocean, is unknown, and up to 2,000 new species are described per year.
Which has more species land or ocean?
Published and unpublished opinions from various sources indicate that terrestrial spe- Page 7 Species diversity: land and sea 377 cies diversity is about 12 million, plus or minus 1 million. In contrast, marine species diversity appears to be less than 200 000.
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)
How do you think that saving oceans can feed the world?
But the potential of healthy oceans to help meet this demand is immense: Estimates suggest that a healthy, fully restored ocean could provide a healthy seafood meal, every day, for more than 1 billion people.
Why is biodiversity important?
Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
Why species diversity is important for the health of marine ecosystem?
A high biodiversity, including species richness, may enhance ecosystem processes and promote long-term stability by buffering, or insuring, against environmental fluctuations (Yachi and Loreau, 1999; Loreau, 2000).
Why is high biodiversity advantageous over low biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
Has the biodiversity in the sea changed?
Biological diversity in the oceans has decreased dramatically since industrialization began in the 19th century. The primary causes for the losses include the destruction of habitats by trawler fishing, pollution and eutrophication of the seas, as well as the steady progress of climate change.
Does the ocean have a high biodiversity?
What is marine 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.
How do coral reefs support biodiversity?
Coral reefs support more species per unit area than any other marine environment, including about 4,000 species of fish, 800 species of hard corals and hundreds of other species. Scientists estimate that there may be millions of undiscovered species of organisms living in and around reefs.
Why are sea animals bigger than land animals?
The largest ocean going animals are larger than any land animals that ever lived because the buoyancy of an aquatic animal allows its weight to be efficiently dispersed. The weight of an animal as large as a whale would make it impossible to survive out of the water.
Why is there more sea than land?
The more granite there is, the more continent there is, and the more of the Earth’s surface rises above the ocean basins. Water fills the basins. Right now, there is more basin than continent, and so more ocean surface than land surface.
Is it easier for organisms to live in the sea or on land?
For example, when considering respiration, it would be ‘easier’ to live on land as it has a more easily accessible source of oxygen, but with regard to thermoregulation, living in a body of water gives a more constant temperature as water is traditionally difficult to heat up.
