- In not more than 200 words or 5 sentences, explain why or why not shark finning used in shark fin soup can induce the destruction of the coral reef ecosystem.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.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?
- Shrimp fishing off the coast of Georgia was closed in 2001, due to a drastic reduction in the shrimp population.

These habitats between open ocean and fresh water are “nurseries” for many marine animals. Speculate about possible causes for the decline in shrimp and blue crab populations.A 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:Which of the following situations is a density - dependent limiting factor? Choose only one. - Dinoflagellates in Laguna de Bay increase in population due to an increase in organic substance in the body of water brought by water pollution.- The oil spill in Guimaras harmed many aquatic organisms in the vicinity.- Super typhoon Haiyan caused many residents to leave Tacloban, Leyte.- Population of civet cat decreases because of deforestation.
- manatees are shallow water herbivores that face increasing threats. Use your know knowledge of seawater properties to describes some of the reasons why manatee populations are in decline. How can we reverse this decline? Please be sure to reference your article (include information about it) in your answer and define any scientific terms your audience may not know.Researchers have suggested that predators could actually increase the population density of a prey species heavily infested by a pathogenic parasite. Explain how predation could lead to population increases in the prey population.An insecticide is sprayed that kills the grass blackberry bushes.explain how each of the other populations of organisms will be affected If all the trees in the area were cut down,the energy supply of which population would be most directly affected?How would an increase in the oriole population affect the ecosystem? How would an increase in grasshoppers affect the rabbit population? Using evidence from the food web,explain why it is called a food"web"
- Define predation. How does the predator-prey relationship differ from the parasite-host relationship? Why is the evolutionary race be-tween predator and prey one that the predator cannot afford to win?In a food web, the numbers of each organism typically exist in a relatively stable proportion. If an oilspill killed a large amount of zooplankton, what would be the next thing that would happen?A The number of tiger sharks would decrease.B The number of phytoplankton would increase.C The number of clams, mackerels, and jellyfish would decrease.D The number of herring, whelk, squids, and loggerhead turtles would increase.Imagine that a certain foreign snake species has been set loose in Mississippi. They are flourishing in their new habitat, however, their effect on native ecosystems has been destructive. Explain the reasons behind this problem. How likely is this example?
