Textbook Question
Chapter 17, Problem 16BS
Coral reefs harbor a greater diversity of animals than any other environment in the sea. Australia’s Great Barrier Reef has been protected as a marine reserve and is a mecca for scientists and nature enthusiasts. Elsewhere, such as in Indonesia and the Philippines, coral reefs are in danger. Many reefs have been depleted of fish, and runoff from the shore has covered coral with sediment. Nearly all the changes in the reefs can be traced back to human activities. What kinds of activities do you think might be contributing to the decline of the reefs? What are some reasons to be concerned about the decline? Do you think the situation is likely to improve or worsen in the future? Why? What might the local people do to halt the decline? Should the more industrialized countries help? Why or why not?

There is an amusement park based on sea life. Its purpose is to get the public interested and caring about
conservation of the world's oceans. Some of the profits from this organization go toward funding ocean research and
conservation. In order to get people interested, some of the shows that the park offers include large marine
mammals that do tricks. Some of the larger marine animals are housed in pools for viewing instead of being allowed
to live in their natural habitat. They also have rare and endangered species on display to help increase awareness of
them. They even have a breeding program for the some of the endangered animals.
Describe an ethical concern that would be related to this park.
Why are coral reefs important?
A: Coral reefs house over 25% of marine species.
B: Coral reefs provide an important habitat for many ocean creatures.
C: Coral reefs create important food webs.
D: All of the above
Entangles fish, marine mammals, and sea birds, preventing them from feeding or causing
them to drown.
Dead zones: algal blooms consume oxygen, kills shellfish and displaces fish.
Poisonous algae and countless plants and animals have invaded harbor waters and
disrupted the local ecological balance.
Destruction of coral reefs.
Of the seventeen major world fisheries, four are depleted and the other thirteen are
either fished to capacity or over-fished.
Ghost nets: lost or
discarded fishing nets
keep on fishing.
Nitrogen and phosphorus
from sources such as
fertilizer, sewage and
detergents, enter coastal
waters.
Invasive species, such as
zebra mussels.
Cruise ships and tourists.
Commercial marine
fisheries.

- Shrimp fishing off the coast of Georgia was closed in 2001, due to a drastic reduction in the shrimp population. Landings of blue crab plummeted in 2002 and 2003, as five years of drought and greatly reduced freshwater flow from underground aquifers led to increased salinity in coastal estuaries. These habitats between open ocean and fresh water are the “nurseries’ for many marine animals. Using information you learned in this lab, speculate about possible causes for the decline in shrimp and blue crab populations.arrow_forwardMore about zonation Click on the question marks to change them to a check mark for each statement that is TRUE or a blank box if the statement is NOT TRUE about vertical zonation. Kelps and corraline algae can be found along the lower intertidal and subtidal zones. ? The lower intertidal is dominated by seaweeds. The first stage of ecological succession in the rocky intertidal is the establishment of bacteria and microscopic algae. Green, brown and red algae on the upper intertidal are able to fix nitrogen from the air. The effect of a keystone species can easily be judged by how abundant it is.arrow_forwardCoral reefs are built from the calcium carbonate secretions of coral polyps, and the resulting structures provide shelter and homes for a diverse group of organisms. However, many of these reefs are decreasing in size, due to the effects of climate change, and the animals that rely on them are in danger of extinction. Which activity would have a negative impact on biodiversity in coral reefs? Developing technologies that would reduce the amount of pollutants produced Increasing use of sustainable technologies Increasing use of fossil fuels Increasing the use of renewable energy sourcesarrow_forward
- Given the data collected by a recent Australian government study on the Great Barrier reef we recognize humans have protected the reef and it is now a model for restoration projects, worldwide. humans are killing the reef through acts of violence so discrete they are unable to be quelled by even military forces. humans are indifferent to the status of the reef. humans are destroying the reef through their own generated pollution. it is a relatively easy task to restore the world landmark.arrow_forwardThe pelagic zone of the ocean is the area of the ocean that is neither close to the bottom nor close to land. There are a wide variety of organisms that inhabit the pelagic zone. Phytoplankton float along the surface, using photosynthesis to produce food. Zooplankton are tiny organisms that float in the surface waters and feed on the abundant phytoplankton. Krill, small crustaceans, also feed on phytoplankton. They display vertical migration in which they swim at deeper depths during the day and then come up to the surface waters at night to eat. What is the relationship between zooplankton and krill? a) Symbiosis b) Competition c) Parasitism d) Commensalism e) Mutualismarrow_forwardFood Webs Food webs are helpful diagrams to understand the relationships of organisms within a biological community.

- Use the passage to answer the question. Great Barrier Reef In a short paragraph, list and describe four different interspecific interactions This photo depicts a section of the Great Barrier Reef in Australia, that could occur in this ecosystem. Your answer should include one (-,-), one which is the world's largest coral reef system and one of the most (+,+), and two different (+,-) interactions. diverse ecosystems in the world. The reef is home to at least 30 B I U E E species of marine mammals and 1,500 fish species, as well as various marine crustaceans, sea turtles, and invertebrates.arrow_forwardCrown-of-thorns starfish (often abbreviated as COTS; Acanthaster planci) is one of the largest sea stars in the world. It is also well known as a voracious predator of corals. Sudden outbreaks or swarms of this one species can rapidly consume an entire coral reef. Use internet resources to investigate recent research articles on the topic of crown-of-thorns starfish outbreaks on coral reefs. Where do these outbreaks occur? What impacts do they have on near-shore ecosystems? What causes these outbreaks? What management practices, if any, could be employed in response to COTS outbreaks?

Boreal forests are dominated by deciduous trees. Lichens are common in the arctic tundra.arrow_forwardOrganisms that live on the surface of rocky shores are called epifauna biomass Rocky Balboa rocksarrow_forwardCoral reefs are unique, living structures. Even though they appear to be hard, rock-like structures, the soft-bodied coral animals that build the elaborate, hard, rock-like reef structures around themselves live inside. Corals are unique animals because they have photosynthetic algae that live inside their cells. This unique relationship is beneficial to the algae since it has a safe place to live inside the coral cells, and it is beneficial to the coral since the algae are producing food via photosynthesis. From the description above, what type of symbiosis is described, and at what ecological level does this relationship exist? The relationship is an example of parasitism, and it exists at the community level. The relationship is an example of mutualism, and it exists at the community level. The relationship is an example of commensalism, and it exists at the community level. The relationship is an example of mutualism, and it exists at the…arrow_forward
