Which reef has the most 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.
Does the Great Barrier Reef have high biodiversity?
The Great Barrier Reef is internationally recognised for its outstanding biodiversity. The world heritage status of the Reef recognises its great diversity of species and habitats.
Do coral reefs have the most biodiversity?
The variety of species living on a coral reef is greater than in any other shallow-water marine ecosystem, making reefs one of the most diverse ecosystems on the planet. Covering less than one percent of the ocean floor, coral reefs support an estimated 25 percent of all known marine species.
Is the Great Barrier Reef one of the biggest ecosystem in the world?
More information. The Great Barrier Reef is the largest coral reef ecosystem on earth and one of the best managed marine areas in the world. At 348 000 square kilometres, the reef is one of the richest and most diverse natural ecosystems on Earth.
Why does the Great Barrier Reef have so much biodiversity?
These became submerged as the sea continued to rise, and the modern reef as we know it started growing somewhere between 6,000 and 9,000 years ago, when sea level stabilised close to today’s level. Over these few thousand years, it’s grown and developed into one of the world’s most diverse ecosystems.
What Makes the Great Barrier Reef so spectacular?
The Great Barrier Reef is unique as it extends over 14 degrees of latitude, from shallow estuarine areas to deep oceanic waters. Within this vast expanse are a unique range of ecological communities, habitats and species – all of which make the Reef one of the most complex natural ecosystems in the world.
What type of ecosystem is the Great Barrier Reef?
The Great Barrier Reef includes the world’s largest coral reef ecosystem with some 3000 coral reefs. Corals are marine invertebrates that are part of the same group as jellyfish and sea anemones. Corals are colonial animals (or polyps), where many coral polyps group together to form a coral colony.
Why do coral reefs have such a high biodiversity?
Coral reefs have high levels of biodiversity because of their abundant microhabitats, high levels of nutrients, and high levels of sunlight and warm…
How much biodiversity has the Great Barrier Reef lost?
Scientists project a significant loss of biodiversity within a decade, and at worst a 95 percent decrease in the distribution of Great Barrier Reef species by late this century.
How much biodiversity is in coral reefs?
Coral reefs are among the most biologically diverse and valuable ecosystems on Earth. An estimated 25 percent of all marine life, including over 4,000 species of fish, are dependent on coral reefs at some point in their life cycle.
How can you describe a high biodiversity in coral reefs?
When biodiversity is high, it means there are many different types of organisms and species. Coral reefs have very high biodiversity—more than 25 percent of all marine species are found on coral reefs, which occupy less than one percent of the ocean.
What is high biodiversity?

Is the Great Barrier Reef still alive?
In 2020, a study found that the Great Barrier Reef has lost more than half of its corals since 1995 due to warmer seas driven by climate change. As global warming continues, corals will not be able to keep up with increasing ocean temperatures.
