Best answer: Is the ocean biodiverse?

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.

Is the sea biodiverse?

Box 1.

‘ The Mediterranean Sea, for example, is one of the world’s hot spots for biodiversity. Its highly diverse ecosystems host up to around 18% of the world’s macroscopic marine biodiversity (Nike Bianchi and Morri, 2000), or potentially over 17,000 species (Coll et al., 2010).

Does the ocean have a high or low biodiversity?

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.

Why is it that ocean is a biodiversity?

Why is marine biodiversity important? … One of the most important functions of marine ecosystems is the production of plant biomass from sunlight and nutrients (primary productivity), which represents the basic food source for all life in the ocean, and ultimately also for humans.

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)

Is coral a reef?

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. … They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas.

What are examples of biodiversity?

The definition of biodiversity refers to the amount of diversity between different plants, animals and other species in a given habitat at a particular time. The different varieties and types of animals and plants that live in the ocean is an example of biodiversity.

Is the ocean acidic or basic?

The ocean’s average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

What part of the ocean 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. However, life does exist in the arctic regions, mostly affiliated with the seas that surround them.

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.

Is the ocean the most biodiverse place on Earth?

In fact, 80 percent of life on Earth is found in the ocean, spread across countless ecosystems throughout millions of square miles covering Earth’s surface. The ocean is amazingly diverse.

What biodiversity means?

The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.

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.

What is in the ocean ecosystem?

The ocean ecosystem includes everything in the oceans, as well as the saltwater bays, seas and inlets, the shorelines and salt marshes. It is home to the smallest organisms like plankton and bacteria, as well as the world’s largest living structure – the Great Barrier Reef, which can even be seen from the moon.

What is the most biodiverse ecosystem in marine systems?

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.
