What is one reason coral reefs are such diverse ecosystems quizlet?
A reef supports many different niches for organisms to live under, on, and among the coral. This enables more species to live in the reef than in a more uniform habitat, such as a flat sandbar. Diversity is important within a species.
Are coral reefs the most diverse?
Coral reefs are the most diverse of all marine ecosystems. They teem with life, with perhaps one-quarter of all ocean species depending on reefs for food and shelter. Because they are so diverse, coral reefs are often called the rainforests of the sea.
Why is biodiversity important in coral reefs?
It provides habitat for nearly 9,000 species of marine life—and that’s just the (relatively) easy to count ones! The reef’s rich biodiversity helps it to maintain a stable and healthy coral reef system. Another way to look at biodiversity is from the perspective of the ‘jobs’ that organisms do within the system.
What are two factors that can damage coral reefs?
Coral reefs are dying around the world. Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays. Other dangers include disease, destructive fishing practices and warming oceans.
What happens if we lose our coral reefs?
The disappearance of coral reefs from our planet could lead to a domino effect of mass destruction. Many marine species will vanish after their only source of food disappears forever. Coral reefs provide protection against flooding and the erosion of coastlines.
How is coral affected by pollution?
Pollution can smother coral reefs, lower water quality, and make corals more susceptible to disease. When sediment and other pollutants enter the water, they smother coral reefs, speed the growth of damaging algae, and lower water quality.
Does plastic cause ocean acidification?
New research has found that pollution from plastic waste dumped into the world’s oceans is correlated with ocean acidification, which occurs when the water’s chemistry is altered as CO2 is absorbed by seawater. Increased ocean acidity is also caused by CO2 emissions being absorbed into the sea.
Is plastic acidic or alkaline?
All plastics up to polymers with macromolecular chains of saturated hydrocarbons possess both acidic and basic properties. Thus, for example, polyethylene terephthalate (PET) according to general assumptions is a base and polyvinylchloride (PVC) and polymethylmethacrylate (PMMA) are acids.
How can we prevent plastic pollution in the ocean?
So, what can you do about ocean plastic pollution?
- Reduce Your Use of Single-Use Plastics.
- Recycle Properly.
- Participate In (or Organize) a Beach or River Cleanup.
- Support Bans.
- Avoid Products Containing Microbeads.
- Spread the Word.
- Support Organizations Addressing Plastic Pollution.
What are the causes of ocean acidification?
Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water’s pH, making the ocean more acidic. Many factors contribute to rising carbon dioxide levels.
Is ocean acidification caused by humans?
The culprit behind the acidification is the extra carbon dioxide humans have caused to collect in the atmosphere by burning fossil fuels, cutting down forests, and other actions.
What is the impact of ocean acidification?
Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve.
How can we prevent ocean acidification?
The most effective way to limit ocean acidification is to act on climate change, implementing solutions to dramatically reduce the use of fossil fuels. If we dramatically cut our global warming emissions, and we limit future warming, we can significantly reduce the harm to marine ecosystems.
How does ocean acidification affect climate change?
If acidification decreases marine emissions of sulfur, it could cause an increase in the amount of solar energy reaching the Earth’s surface, speeding up warming—which is exactly what the Nature Climate Change study predicts.
