Where is most marine biodiversity found?

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.

Where is the greatest marine biodiversity located?

The greatest marine biodiversity occurs in coral reefs, estuaries, and on the deep-sea ocean floor. 2. Biodiversity is higher near the coasts because of great variety of producers, habitats, and nursery areas.

Where are most marine species found?

Most marine life is found in coastal habitats, even though the shelf area occupies only seven percent of the total ocean area. Open ocean habitats are found in the deep ocean beyond the edge of the continental shelf. Alternatively, marine habitats can be divided into pelagic and demersal zones.

Which country has the richest marine biodiversity?

Tropical reefs are the richest marine ecosystems on earth and those found in the Philippines boast a diversity of life and colour that is unparalleled. The Philippines is part of the Coral Triangle, the epicenter for marine biodiversity and what is considered the Amazon of the Sea.

Which marine habitat has the most biomass?

Most of this biomass is found on land, with only 5 to 10 billion tonnes C found in the oceans. On land, there is about 1,000 times more plant biomass (phytomass) than animal biomass (zoomass).

What is the biggest source of coastal pollution?

The majority of pollutants that make their way into the ocean come from human activities along the coastlines and far inland. One of the biggest sources of pollution is nonpoint source pollution, which occurs as a result of runoff.

Where do most fish live in the ocean?

Most species live on the sea bottom in relatively shallow waters, although species are known from mid and deep water, from the mid-water, and even from fresh water.

Where are the fewest marine animals found?

Most undiscovered creatures likely remain in the least explored habitats such as the deep oceans, the most diverse environments such as tropical shallow seas, and the most diverse groups including molluscs and crustaceans.

86% of the worlds Biomass is located in the global south, also known as Brazil. Very little Biomass is Found in the United States. Sub-Saharan Africa comes behind Brazil with 2nd largest amount of Biomass.

Where is the most biomass found in an ecosystem?

For animals, most biomass is concentrated in the marine environment, and for bacteria and archaea, most biomass is concentrated in deep subsurface environments.

What is most of the oceans biomass?

The oceans contain much more consumer biomass (≈5 Gt C) than producer biomass (≈1 Gt C). Unicellular organisms contribute approximately two-thirds of the total biomass of marine organisms. … Plants (green algae and seagrasses), fungi, and archaea each account for less than 10% of the global marine biomass.
