- Since diatoms are autotroph & dinoflagellates are mixotroph, how will this affect the distribution of each species in the ocean?What is the role that diatoms, dinoflagellates, and green algae play in marine and fresh water ecosystems?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? Explain
- How are diatoms and dinoflagellates used in monitoring water quality? Cite two (2) examples.You have discovered a new species aquatic protist that is a primary producer. It cannot swim on its own. It appears to be resistant to physical damage from wave action due to the presence of a glass-like wall. Which of the following organisms would this organism be most like? A) diatom B) dinoflagellate C) apicomplexan D) red algaMutualisms are interactions between two species where both participants benefit. How might the relationship between a sponge with glassy spicules and microalgae or cyanobacteria be a mutualism?
- Dinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night. During the day, they carry out photosynthesis similar to other autotrophs. At night, however, they bioluminesce every time they are disturbed. They are often seen in the wakes of ships at night. While the reason for this bioluminescence is not fully understood, many scientists concur that it is a form of self-defense. If small fish begin to feed upon the protists, the protists will begin to bioluminesce. These flashes of light in the dark water can alert larger fish and draw them towards the small fish, upon which they prey. By making the small fish vulnerable, the dinoflagellates are able to protect themselves. Based on the information above, a researcher decides to design an experiment in which she is testing how long it takes for dinoflagellates to recover after different amounts of disturbance. She maintains 10 containers of dinoflagellates with similar temperature, salinity and…Dinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night.
