- 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.Coral reefs are being threatened and/or damaged by all of the following, except discharge of industrial waste trash warming ocean waters discharge of sewage too much sunlightPlasmodium is a vector for mosquitos. It is a protozoan that is the causal agent of malaria, which is responsible for killing as many 855,000 people in 2013, the majority of them being children. Populations of mosquitos are strongly influenced by the availability of standing water for egg-laying and larval development. How might mosquito density, and thereby human mortality, be affected by patterns of rainfall?
- Visit the ANEMONE page:http://www.aquariumofpacific.org/onlinelearningcenter/species/clown_anemonefish10. What type of symbiotic relationship do clownfish and anemones exhibit: mutualism, commensalism, or parasitism? Explain.11. How are clown fishes protected from the paralyzing sting of the anemones?https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html Now you'll tie together what you've learned. Read over the information on what's happening with the study of lionfish (you can ignore the questions on this page). Answer the question here on Canvas. 18)Based on what you've learned about the invasive lionfish population in the Atlantic, and the various types of factors that may limit population growth, which ONE factor (intraspecific competition, interspecific predation, disease & parasites, social behavior) do you think would be the MOST limiting? Why?Mutualism is defined as a close, prolonged association of two or more species that is of benefit to allparticipants. Explain how the relationship between the bobtail squid and Vibrio fischeri is an example ofmutualism. Defend your claim with evidence.
- Why are coral reefs not found in the regions from west bengal to andhra pradesh but are found in tamil nadu and on the east coast of india?Which row below best describes why the population of adult mosquitoes would drop so dramatically during this time period Feb. 5, 2007 Something is wiping out honey bees across North America and a team of researchers is rushing to find out what it is. What’s being called Colony Collapse Disorder (CCD) has now been seen in Pennsylvania, North Carolina, Florida, Georgia and way out in California. Some bee keepers have lost up to 80 percent of their colonies to the mysterious disorder. Whatever kills the bees targets adult workers, which die outside the colony — with few adults left inside, either alive or dead. The disorder decimates the worker bee population in a matter of weeks. Aside from making honey, honey bees are essential for the pollination of tens of million of dollars worth of cash crops all over the United States. That’s why almond growers of California, for instance, are taking notice and pledging funds to help identify and fight the honey bee disorder. Among the…forest sites than in forest fragments, whereas there were no significant differences between fragments of different sizes. These results provide further evidence for the effects of habitat size on the phorid-Acromyrmex system in a tropical rain forest, based on the abundance of parasitoids both as adults in the field and as reared immature phorids in the laboratory. Phorid parasitized leafcutter ants were most abundant in areas of continuous forest, and less abundant in the forest fragments. O Phorid flies are important parasitoids of leafcutter ants nd leafcutter ants can be found in Brazil's Southeastern Both phorid flies Atlantic Forest. The study provides evidence that this parasitoid-host interaction between phorid flies and leafcutter ant differs between continuous forest and forest fragments. Phorid flies were just as abundant in forest fragments as they were in continuous forest, but were less successful in parasitizing leafcutter ants.
