How oceans are the home to the greatest biodiversity?

The ocean is home to a phenomenal diversity of marine organisms. They have evolved to inhabit warm waters near the equator and the icy waters of the Earth’s poles. Marine life takes advantage of the enormous volume the ocean comprises: from diatoms living near the sunny surface, to octopods living in the dark deep sea.

Why are oceans important to biodiversity?

Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation. …

How do you think that seas are the home to greater biodiversity than oceans?

Answer: 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 does the ocean support diversity?

The ocean provides a vast living space with diverse and unique ecosystems from the surface, through the water column, and down to and below the seafloor. For example, coral organisms facilitate an exceptionally biodiverse ecosystem (Fig. 1.6).

Where in the ocean has the greatest 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.

What is ocean biodiversity?

The ocean is amazingly diverse. Life in the ocean ranges from the smallest microscopic bacteria and viruses to the largest animal ever to have lived on Earth—the blue whale. Biodiversity refers to variation among living things within an ecosystem. This includes variation in plants, animals, fungi, and micro organisms.

Why are oceans marine relevant?

Oceans are an important source of food. They host 80 percent of the planet’s biodiversity, and are the largest ecosystem on Earth. … Only ten species provide about 30 percent of marine capture fisheries and ten species provide about 50 percent of aquaculture production.

Are there more living things in the ocean or on land?

By one estimate, there are five times as many terrestrial species as marine species today. … Scientists now estimate that 80 percent of Earth’s species live on land, 15 percent in the ocean, and the remaining 5 percent in freshwater.

Is there more diversity on land or in water?

It has long been known that there are far more species living on land than in the sea. Although the oceans cover a little >70% of Earth’s surface, they account for only a small fraction of nonmicrobial species, estimated at anywhere from 5% (Benton 2009) to 15% (May 1994). Most of the remaining species reside on land.

Is there more sea than land on earth?

Answer 1: It has to do with the different kinds of rocks in the Earth’s crust: continents are made of granite, and ocean crust is made of basalt. Right now, there is more basin than continent, and so more ocean surface than land surface. …

Why are oceans 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 is the ocean diverse?

Diversity among ecosystems

Due to its vast depth, there are many locations in the ocean in which humans have yet to explore. For example, the deep sea is located at 1800 metres or more below the ocean’s surface and little to no light is able to penetrate this habitat.

How does the ocean support life?

The ocean plays a fundamental role in supporting life on Earth by regulating our climate. It does this by storing and transporting huge amounts of heat, water and greenhouse gases (such as carbon dioxide). … However, this comes at a cost to ocean health and therefore human health.

Which of the following habitats has the greatest biodiversity?

Answer: Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
