Coral reef symbiosis Watch the video: Exploring ecosystems- Coral reef symbiosis Pause the video at spots where requested and in groups of three, discuss and write down your predictions. 1. A. What type of relationship is there between the bubble-tipped anemone and the clownfish? B. What is the relationship between the butterflyfish and the anemone? 2. A. Given the data at the first pause ( at time= 2:05), what mathematical relationships (biotic factor about the distribution of organisms) do you see between the two species? ______Bubble-tipped anemone to ____ clownfish B. Give a reason why it is that ratio is not 5 to 1, or 4 to 1. 3. A. Based on the new data for year 2014 and 2015 at the second pause ( at time= 2:51) predict the number of clownfish. B. Where do the rest of the clownfish go? C. Discuss why they do not distribute 3, 4, or 5 clownfish to each anemone. 4. A. What is the mathematical trend for the entire set of data between temperature (an abiotic factor) vs. anemones; and temperature vs. clownfish? B. Which do you think is directly affected by the temperature, the fish or the anemone? C. As temperatures rise how will this affect the food chain? D. Will the population of white tipped sharks be affected? Give a reason why or why not. 5. A. At minute 3:21, why is the white tip shark not aggressive toward the bluestreak wrasse? B. What kind of relationship is this and why? C. How does the shark know not to eat this fish? 6. A. The saber-toothed blenny looks like a cleaner wrasse, but what is it’ s relationship to the larger fish? B. Is it a coincidence it looks the cleaner wrasse? Give an evolutionary reason how this could have occurred. C. This color pattern of the saber-toothed blenny is known as what? 7. Watch the video: https://www.youtube.com/watch?v=tZuxZdG6TfM A. What is coral and which organism(s) is it made from? B. In the nutrient poor shallow waters of the ocean that contains coral, what is it that the coral are able to eat? C. From where does 75%- 95% of the food for coral originate? Where does most of the energy come from? D. Where are the producers found in a coral reef? E. What give coral its different colors? F. What kind of relationship exists between symbiotic algae and the coral polyps? G. Because they also eat zooplankton, they are also a __________________ consumer. H. Reason as to what trophic level coral are on. Are they actually producers or first or second level consumers? Youtube: Parrotfish Critical for Healthy Coral Reefs A. What do parrotfish eat? B. Does that make them good for the reef system or bad? C. What abiotic factor do they contribute to the reef that the tourists enjoy? D. Are they first level consumers or second level consumers? Explain. 8. Find the you tube video: Parrotfish Critical for Healthy Coral Reefs A. If parrotfish eat the healthy coral, then how does overfishing for them cause the reef to die off? What role do the parrotfish play in keeping the reef alive and growing? B. How did cores of ancient coral, tell the story that the more parrotfish there were, the better the reef grows? What is the evidence given? 9. Coral Bleaching https://www.youtube.com/watch?v=_ZfGIKiSwwQ https://www.youtube.com/watch?v=kNB-2AgIMIE A. Find what factors are causing coral bleaching? B. When corals bleach what happens to make them lose color? C. How would this affect the productivity of the reef system? D. Using information from the previous videos explain. https://www.marinebiology.org/coralbleaching.htm read
