Step by step
Solved in 2 steps
- 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?What is the difference between commensal and parasitic associations? Give an example of a marine commensal association/relationship that has the potential to become parasitic.What is the impact of coral bleaching on biological diversity in marine ecosystems?
- Discuss the phrase “Sponges work well with so little.” In what particular instance would this be applicable in the life of a sponge? Cite specific examples ( 3) and explain briefly. Discuss the potential use of sponges as monitors of chemical pollutant stress in marine and freshwater ecosystems. Use concepts learned in Ecology. Most sponge species are of leuconoid construction, is this type of sponge construction an advantage or disadvantage?Relative to topsoil with a strong population of nematodes, soil without nematodes would most likely have greater erosion. retain water more effectively. have higher nitrogen levels. have lower availability of nutrients. have lower oxygen levels.What is the photoaxis of zooplankton at surface conditions of low salinity?
- With the aid of life-cycle diagrams, describe the different types of sexual reproduction in marine macroalgaeDescribe three specific interactions of anemones with nonprey organisms.How are diatoms and dinoflagellates used in monitoring water quality? Cite two (2) examples. What are zooxanthellae? Describe their role in symbiotic relationships.
- This is marine biology a) Where do macroalgae tend to live? Middle of the ocean or continental shelf? Why? b) What are two examples of “stiff” algae? What are they made of and what phylum do they belong to? c) What colors do green algae use for photosynthesis? What color do they NOT use? d) Which algal phylum is best adapted to deeper water? Why?e) Would you rather go swimming at a Japanese beach or a California beach? ExplainWhat is the role of Charadrius melodus in the ecosystem?What is the importance of gliding motility in theformation of marine chemolithotrophic mat systems?
