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?

Lionfish are native to the Indo-Pacific, which includes some of the most biodiverse marine areas on Earth. In the video about lionfish in the Atlantic, however, you learned that lionfish have devastating effects on the biodiversity found on coral reefs in the Atlantic. In about 2-3 sentences, why do you think this might be the case?
Which marine zone would have the lowest total rate of photosynthesis?
photic
littoral
abyssal
pelagic
intertidal

- The benthic zone is home to organisms which are photosynthetic. intertidal. heterotrophic. adapted to high light. Some ecosystems develop a vertical structure (such as seen in a tropical forest). The cause of this is due to competition for which resource? nitrogen minerals moisture carbon dioxide light The biome that is characteristic of Bronx County is a taiga. temperate deciduous forest. temperate rain forest. desert. coniferous forest.arrow_forwardA private reptile breeding facility near the Everglades was destroyed by Hurricane Andrew in 1992. This event contributed to the original influx quantities of pythons in the wild. Pet owners also contributed to the introduction of these reptiles to the Everglades by releasing pets that had grown too large to care for. These reptiles are considered species to this ecosystem. can someone please write an explanation that describes the impact of the Burmese python on the Everglades? Claim: Evidence: Reasoning:arrow_forwardThe _______________ is open ocean from the shoreline to a depth of 200 m. (a) benthic environment (b) intertidal zone (c) neritic province (d) oceanic province (e) aphotic regionarrow_forward
- Figure 44.12 Which of the following statements about biomes is false? Chaparral is dominated by shrubs. Savannas and temperate grasslands are dominated by grasses. Boreal forests are dominated by deciduous trees. Lichens are common in the arctic tundra.arrow_forwardWhere would you expect to find the most photosynthesis in an ocean biome? a. aphotic zone b. abyssal zone c. benthic realm d. intertidal zonearrow_forwardShrimp 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_forward
- Research has traditionally focused on the influence that sediment type has on a community of benthic plants and animals. We are now beginning to understand that it is not so simple. Biological processes are intricately connected to physical processes in the ocean and _________ may strongly influence both sediment and community structure. a. Marine organisms b. Hydrodynamics c. Geomorphic features d. Chemical processesarrow_forwardThe resource page discusses an increasing threat of nuisance flooding in North Carolina. To understand what nuisance flooding is, you have to have a basic understanding of tides. How are tides generated and propagated around ocean basins? Explain how the factors that control tides change over the course of one month and tie that back to the problems with nuisance flooding. Please be sure to reference your article (include information about it) in your answer and define any scientific terms your audience may not know.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 reefsare 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? 1.Increasing use of fossil fuels2.Developing technologies that would reduce the amount of pollutants produced3.Increasing use of sustainable technologies4.Increasing the use of renewable energy sourcesarrow_forward
- The balance of the coral reef ecosystem is being affected by warming oceans, changing ocean currents, and what other external factor? A: The acidification of the oceans B: The light that enters the system C: Marine animals leaving the reef D: Not enough information is givenarrow_forwardHow does hydrology influence the physical character of a place? Select all that apply. Responses Tidal marshes allow for a multitude of flora and fauna. Hydrology studies the ocean currents and water temperature. Floods create new groundwater ecosystems. Fjords, created by glaciation, create deep water for fishingarrow_forward_______ are sometimes called "nurseries of the sea because of the large numbers of animals that use them for breeding purposes.
