Do marine ecosystems support a high or low diversity of life?

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. Fig.

Does the ocean contain high or low ecosystem diversity?

Ecosystems based upon water can either be highly diverse or have a very low biodiversity. The ecosystems that are marine, or made up of saltwater, include coral reefs and the intertidal zone, which are both highly diverse, as well as the open ocean, which has a fairly low biodiversity.

Does the ocean supports a great diversity of life and ecosystems?

#5: The ocean supports a great diversity of life and ecosystems. The ocean is the largest living space on Earth, home to creatures ranging in size from microbes to blue whales. Variations in physical conditions like light and temperature create many different habitats across the global ocean.

Does the marine have high biodiversity?

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.

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.

Why do oceans support different ecosystems?

There are many different ecosystems within the ocean depending on conditions such as the water temperature, the amount of sunlight that filters through the water, and the amount of nutrients. … Others are able to survive at a range of temperatures and can live in more places in the ocean.

What is diversity in marine?

Marine diversity is defined as the variety of life forms distributed in the worlds oceans and seas which is enormous.

What ecosystems does the ocean support?

Although there is some disagreement, several types of marine ecosystems are largely agreed on: estuaries, salt marshes, mangrove forests, coral reefs, the open ocean, and the deep-sea ocean. An estuary is a coastal zone where oceans meets rivers.

What makes an ecosystem with high biodiversity low biodiversity?

When an ecosystem has high biodiversity it is always more stable than an ecosystem that has low biodiversity. … Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.

Why is marine 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.”

What do ecosystems with high biodiversity have?

What is marine life biodiversity?

What is marine biodiversity? Biodiversity is an all-inclusive term to describe the total variation among living organisms of our planet. In its simplest form, biodiversity or biological diversity is therefore ‘Life on Earth’ and includes marine biodiversity ‘Life in the Seas and Oceans.

How do coral reefs support biodiversity?

Approximately half a billion people globally depend on coral reef ecosystems for food, coastal protection, and income from tourism and fisheries. Healthy coral reefs provide: Habitat, feeding, spawning, and nursery grounds for over 1 million aquatic species, including commercially harvested fish species.
