Why are marine biologists concerned about the changes shown in the graph? Increasing water temperatures can lead to coral reef declines. Marine mammals and birds are susceptible to being entangled in and strangled by larger pieces of plastic.

How will the loss of coral reefs affect the marine ecosystem?

For these creatures, the reef provides essential food, shelter and the spawning grounds needed for their species’ survival. If their homes disappeared, marine biodiversity would suffer immensely. And, like a domino effect, many fish, turtles and other creatures would disappear.

Why are coral reefs important for ocean ecosystem?

Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.

What are the effects of ocean acidification on coral reefs?

In order for a coral reef to grow, it must produce limestone (or calcium carbonate) at a rate that is faster than the reef is being eroded. Ocean acidification slows the rate at which coral reefs generate calcium carbonate, thus slowing the growth of coral skeletons.

Why would these organisms most likely be found in deeper ocean zones?

Why would these organisms most likely be found in deeper ocean zones? There is less light in deeper ocean zones. A scientist discovers a new species of marine bacteria that do not require oxygen to survive. In fact, dissolved oxygen in the water is actually toxic to these bacteria.

Why would these organisms likely be found only in shallow ocean zones?

Why would these organisms likely be found only in shallow ocean zones? The amount of light in deeper ocean zones is too dim. Cyanobacteria are organisms that use the sun’s energy to produce their own food. During a storm, a population of cyanobacteria was carried down into a deeper layer of the ocean.

What would happen if all marine life died?

Gone will be all of the ecosystem services those organisms provide, such as filtering water (a single mussel or oyster can clear up to 10 gallons of seawater a day), building a moist habitat for a diverse assemblage of other species and providing food for species at higher levels on the food chain, like crabs, birds …

What would happen if we lost all coral reefs?

If coral reefs disappeared, essential food, shelter and spawning grounds for fish and other marine organisms would cease to exist, and biodiversity would greatly suffer as a consequence. Marine food-webs would be altered, and many economically important species would disappear.

Is the Great Barrier Reef dead?

The Great Barrier Reef has been one of the jewel tourist destinations in Australia for decades. Known as the largest reef ecosystem on the entire planet, home to thousands of marine animals and coral species.

Why is it important to protect and conserve coral reefs?

Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people. Coral reefs teem with diverse life. Thousands of species can be found living on one reef.

Can you eat coral?

It’s not safe to eat coral because many types of coral contain toxins known as Palytoxin. This chemical is released as a defense mechanism to deter predators. This toxin can cause breathing issues, stomach discomfort, indigestion, and more. In some cases, it’s potentially fatal for people who own large coral aquariums.

How do coral reefs protect coastlines from storms and erosion?

Coral reefs provide a buffer, protecting our coasts from waves, storms, and floods. Corals form barriers to protect the shoreline from waves and storms. The coral reef structure buffers shorelines against waves, storms, and floods, helping to prevent loss of life, property damage, and erosion.

How is climate change most significantly affecting coral reefs and sea life?

A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease. Sea level rise: may lead to increases in sedimentation for reefs located near land-based sources of sediment. Sedimentation runoff can lead to the smothering of coral.

Why is ocean acidification a problem?

Ocean acidification is expected to have negative overall effects on many marine species. This could alter marine food chains and food supply to humans. Acidification could also decrease storm protection from reefs, tourism opportunities, and other benefits that are difficult to value.

What are the threats of coral reefs?

Coral reefs face many threats from local sources, including: Physical damage or destruction from coastal development, dredging, quarrying, destructive fishing practices and gear, boat anchors and groundings, and recreational misuse (touching or removing corals).

Who was the first marine biologist who was the father of oceanography?

Aristotle was a polymath and a great observer interested in zoology and marine creatures. He distinguished about 500 species of animals, arranging them in his book ‘History of Animals’ in a graded scale of perfection with man at the top.

Which of the following technologies allowed marine biologists to descend below the surface and observe marine organisms in their environment?

Using scuba, marine biologists could, for the first time, descend below the surface to observe marine organisms in their natural environment (Fig. 1.8).

What are people who study the ocean called?

An oceanographer studies the ocean. Oceanography covers a wide range of topics, including marine life and ecosystems, ocean circulation, plate tectonics and the geology of the seafloor, and the chemical and physical properties of the ocean.

Which of the following questions Cannot be answered by the scientific method quizlet?

The scientific method cannot be used to answer questions about immaterial and philosophical issues.
